How do I get better at Pre-Algebra?

To get better at any kind of math, you must take time to practice. Video lessons are not enough. If you want to ace Pre-Algebra, look for a stand-alone course that includes practice problems with complete audio explanations along with printable extra problems and notes.

I qualified for my goal of College Algebra. I haven't taken a math class since 2004 and have always disliked it. I found your Accuplacer QAS and AAF lessons to be easy to follow and actually looked forward to them. I liked that the videos and lessons were short so that I could stay focused with review questions at the end. I am very happy with my results, and I would recommend this course to anyone wanting to prepare for the test. i’m

Mathhelp was very helpful. I never went past Algebra 1 in High School, and then 7 years later I needed to place into precalculus to pursue my first college degree. I studied through all of the ALEKS Mathhelp lessons, and then I got a 64 on the test, placing into the math class I needed to be in.Thank you so much for all the help.

I passed the Accuplacer! Thank you for the help. The way the course was set up felt like I was in a real classroom, where I could see the work being done with tips and tricks here and there. The practice questions after the introduction helped alot as well. I will definitely sign up again if I need math help again. The lessons on fractions, and all algebra lessons helped the most. Honestly, the whole course helped especially after not having math for 5 years.

I'm a returning college student who hasn't taken a math class in nearly 5 years. I felt like I needed somewhere I could build on my fundamentals, so I turned to MathHelp. I started with the first ALEKS lesson on MathHelp, watching all the videos, and taking every test until I could pass with a 100% all the way up to the end of exponential and logarithmic equations, which was lesson 179. Overall, I'm very satisfied with my time using MathHelp. Topics I remember as being complicated, like logarithms, were actually very easy to understand thanks to the short video format of the lessons. Recently I took the ALEKS placement assessment and scored well enough to place into pre calculus. I’m impressed I was able to do that well, going from barely remembering the fundamentals of algebra to nearly placing into calculus.

I subscribed to the course for my daughter who needed extra help in algebra 2. She found it very helpful. I would say that hearing the material taught by someone other than her school teacher and having all the extra exercises available to do were the most helpful for her. I can’t think of anything you could do to make it better.

I absolutely love MathHelp. I had not taken a math class in over 30 years and math has always been a difficult subject for me, so for me to be able to prep for the PERT test, place into College Algebra, and then get an A in the class - that was amazing! I have recommended MathHelp to friends and family and will continue to do so.

I am so glad I found your program - it helped me so much. I've been out of school for over 20 years and I recently enrolled in the Kansas State dietetics program. I was freaking out over the algebra placement exam because I couldn't remember anything. After completing your program, I scored a 34 (I only needed a 21 to get into college algebra). So, thank you for your great program, I couldn't have done it without you 😃

I am a 50+ who decided to go back to school late in life. I need to take College Algebra to obtain my degree. To avoid prerequisite math classes, I needed to pass their placement test.It has been a “a few years” since I took a math class. I needed to study and searched for online courses. I came across many sites, but had the best setup, so I signed up. The course covers everything you will need to know. I went through the entire course and took the final exam a few times as reinforcement.The courses are put together in an easy-to-follow manner and provide everything you will need to pass any math test. The layout was easy to follow. The video, followed by practice, followed by the questions were so easy to follow. It is all on one page. There is no navigating back and forth. If you get one wrong, you are given a step-by-step explanation on how to get the correct answer. The reinforcement of each concept is helpful. The videos really make it so easy to learn. The three instructors are great and teach each subject clearly and in a detailed manner.Whether your child is struggling in elementary school, or you are a college student who needs some extra help, is the solution to your needs.I aced my placement test. I now feel fully prepared for the College Algebra class I'm taking next semester. I highly recommend this course.

My College Algebra course went well thanks to your program. The most helpful elements to me were the multiple videos of explanations that started off extremely basic and built up difficulty. I do not learn very well when I get blasted in the face with information then an overly difficult problem. Also the practice tests helped with learning and then performing which helped me retain the lesson.

I was attempting to place into calculus I and I did achieve that. I scored an 85 on the ALEKS. I was a very poor student in high school just so you understand the full picture. I'm trying to catch up on things I should have had a basic foundation in back then. So it was really nice to have a refresher course on all the rules and properties of math and algebra leading up to the calculus portions. Overall, I think the material was very well put together on your site. Clear and concise.

WONDERFUL PROGRAM!! Our first year of homeschooling and the program we were using left my daughter in tears over her 10th grade Geometry. We switched to Math Help and glad we did!! The teachings were easy to understand and kept at a good pace, not overwhelming. She got her Geometry credit without tears!! Thank you Math Help for offering this service! Well done!!

As a math-phobe, I needed as much help on the FTCE math test as could get. A teacher at my school suggested your program. I loved your back-to-basics approach to help someone like me, a 58-year-old who never liked or could do math. I found your instructions and lots of practice questions and tests to be extremely helpful. I took many of the questions over and over again to get the steps correct. I always especially had trouble with measurements and geometry, and I think your program helped ease my anxiety and confront those questions head on. It also helped me get straight in my head the positives/negatives and when they apply in addition, multiplication, etc., as well as how to take a word problem and make it into a solvable algebra equation. It was an extremely helpful program for me. Keep up the great work!

That course was the absolute reason in my success of the TSIA2 test. I did pass it and can take College level algebra instead of developmental math. Specifically speaking, the quadratic equations, functions/graphing, linear equations in two variables and expressions, equations and formulas really helped. So I'd most definitely give that course a lot of credit to helping me pass.

The Accuplacer Elementary Algebra exam went really well. I was able to place into my appropriate college algebra class, and I surprised myself with my score even. I had not been in school for years and the courses on MathHelp made jumping back in so much easier. There were so many helpful elements of the course. The instructional videos and the practice exam were instrumental in helping me.

I passed my college algebra course with an A, thanks to your online course! The explanation in the videos were very detailed and easy to understand; the quizzes really drove the information home into my mind. It felt good going into a quiz and being confident in knowing how to do the problem, with time to spare to check my work, then seeing high marks in my grade book after.I am an adult student, (working and going to school) coming back to college algebra from a long time away from school! I really needed a refresher.It is a vast improvement in my understanding of math (I was not too great with math in general in elementary and high school). Thank you for giving me a boost in "mathematical confidence"! Thank you so much!

I’d like you to know that I absolutely love the Intermediate Algebra program, and will likely be signing back up in January for the College Algebra course. I’m 36 years old and have always struggled with math, barely graduating high school because of it and so I began with your program for the PERT test, which allowed me to get a high enough score to pass taking a remedial course.Continuing with the Intermediate Algebra program during the semester is absolutely the reason why I was able to sustain a B grade, and I actually have my final this afternoon and I am confident I will do well.I think the reason that your program works so well is because you keep it short and to the point. All the steps are shown, you don’t use a bunch of extra words and jargon, and you keep the problems simple so the student gets a chance to perfect those before going on to more difficult ones within their actual class assignments. There were several places where the things you taught weren’t explained in class notes by my school that made a world of difference (such as clearing the radical in the denominator, or using a factor tree to factor rather just trying to guess multiples). It also helped that your course guide exactly followed the flow of the class going from chapter to chapter so I could watch my class lecture (online course), attempt some of those problems...I’d struggle, then I’d go to Mathhelp, do well, and go back to the class coursework. It was an easy lateral movement. My not getting an A in the class is simply because I make silly mistakes like forgetting signs or the simplest math errors, but I feel confident in the course and that’s simply 100% from your program.Thank you for all the help your program has offered, it’s been quite an amazing transformation for me.

Thank you so much for this algebra course!!! I am enrolled in an online college degree program at Penn Foster College. I am a Graphic Design major, but they stuck me in an algebra class. I do NOT have a mind for math, I barely made it through math in school. So this class has been devastating for me, my entire degree depends on this one class! I have never had algebra in my entire life and they put me in Intermediate Algebra right off the bat! Oh, did I mention that they do not actually teach the classes they offer, they send you the text book, and you are literally on your own. Your classes are a lifesaver! I thought I was looking at Chinese, but your step by step lessons actually made sense. If it weren't for you I would have flunked out a long time ago, and lost any chance to get the degree that I have worked so hard on. You are providing a much needed service, THANK YOU SO MUCH!!!

Let me start off by saying how fantastic this website is. During Algebra in 9th grade, I was struggling and needed extra help. When distance learning started due to the pandemic, I was even more stressed and I needed help somewhere, this is when I found I tried the free trial and within an hour, I was highly impressed. I could go to the lesson my teacher was teaching and get extra help which was amazing and I was caught up until school ended. From there, I wanted to do even more math so I used this site the entire summer and I am taking the second half of Algebra this year. With all the work I put in over the summer, Algebra is now a breeze and I am so far ahead and am currently doing the geometry course too! This site is amazing, the presenters explain stuff very well and there's no room for confusion in my opinion.

How do you study for Pre-Algebra?

To study for Pre-Algebra, it is essential to practice after each new lesson. The best approach is to use an online course that provides all of the features listed below.

  1. Video instruction
  2. Background lessons
  3. Guided practice
  4. Printable lesson notes
  5. Printable worksheets for extra problems
  6. Diagnostic quizzes
  7. Interactive tests
  8. Cumulative review
  9. Comprehensive grade reports

What grade level is Pre-Algebra?

Students typically take Pre-Algebra as their 7th or 8th grade math course. However, it might also be offered in 6th grade for those on an advanced track or in 9th grade for students who need more time. Many adults also take the class before attempting college level math.

Why is Pre-Algebra so hard?

The reason the course might seem hard is that it requires algebraic thinking, which is often new for students. Moreover, working with ratios and proportions may be difficult, especially for those who have not mastered fractions. Look for Pre-Algebra help that includes background lessons to build foundational skills and online instruction to guide you along the way.

Is Pre-Algebra harder than Algebra?

Pre-Algebra can seem harder to students because it’s the first time they’re asked to think algebraically. However, Algebra is generally considered to be a harder class because it includes more concepts at a more complex level.

What is taught in Pre-Algebra?

In Pre-Algebra lessons, students are taught the skills necessary to be successful when they move on to Algebra and subsequent math courses. A study guide for this class should include the following concepts.

  • Operations with whole numbers, integers, fractions, and decimals
  • Powers and roots
  • Properties of real numbers and order of operations
  • Ratio, rate, proportion, and percent
  • Algebraic thinking such as patterns, variables, simplifying expressions, and solving equations
  • Geometry concepts including lines, angles, polygons, measurement, area, volume, and the Pythagorean theorem
  • Data representation, basic statistics, and simple probability

Is Pre-Algebra necessary?

Although it may not be necessary for every student to take Pre-Algebra, it provides a solid foundation that’s critical for success in future math classes. It also helps students overcome the initial difficulties they often experience in Algebra.

What should I learn before Pre-Algebra?

Before taking Pre-Algebra, you should have a solid foundation in arithmetic skills as well as familiarity with the skills listed below. A math program covering these concepts will get you ready to pass the course.

  1. Perform operations with whole numbers, fractions, and decimals
  2. Convert between fractions, decimals, and percents
  3. Solve word problems using the four operations
  4. Evaluate numeric expressions with exponents
  5. Compare numbers using inequality symbols
  6. Basic knowledge of geometric shapes and measurement such as perimeter and area
  7. Recognize patterns

What comes after Pre-Algebra?

After Pre-Algebra, which provides the basic skills, students are ready to take high school math. The usual high school sequence is shown below.

  • Algebra 1
  • Geometry
  • Algebra 2
  • Pre-Calculus
  • Calculus (offered in special high school programs)

How do you solve Pre-Algebra problems?

If you’re wondering how to do Pre-Algebra problems, one way is to follow the steps in the examples provided in your textbook. If you have trouble working with a traditional book, an online program that provides guided practice along with audio explanations might be a better approach.

Can you learn Pre-Algebra by yourself?

With enough instruction and practice, you can learn Pre-Algebra by yourself. A curriculum with a teacher inside every lesson, as well as diagnostic quizzes, cumulative review, and interactive tests is a great way to get all the help you’ll need.

How much does a Pre-Algebra tutor cost?

The average cost for a Pre-Algebra tutor is $50 per hour. However, depending on where you live and the qualifications of the instructor, the cost can vary from $25 to $100 per hour. Fortunately, there are also online options that offer the effectiveness of private tutoring at a more affordable price.

What makes Pre-Algebra from MathHelp different?

Unlike other programs, MathHelp was developed by a teacher from one of the top private schools in the country. The instruction and practice are therefore of the highest possible quality. Homeschool families can immediately upgrade their math curriculum to a world-class level, and any parent can provide his or her child with the equivalent of a $20,000-a-year private school education for a tiny fraction of the cost.
