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 Mathhelp.com 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, Mathhelp.com 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!

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 mathhelp.com. 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.
21:35 11 Nov 20
I loved this program. I didn’t do Math in 13 years so I subscribed to MathHelp two months before I started my Intermediate Algebra class. I was ahead of the lessons and I would always come back to MathHelp as my primary source for understanding a topic.. explanation was clear, the teachers were awesome, my favourite was the gentleman.. he thought so clearly that I understood and then I made sure to practice and practice and practice. I received a B+ in my Intermediate Math Course

I found the College Algebra course to be EXTREMELY helpful. I thought every concept was explained in a way that was easy for me to understand. I am currently enrolled in a College Algebra course at a university after spending over 15 years out of school. I tried to take the same course in spring of 2019 and was completely lost because I didn't remember any of the fundamental concepts. I feel like the course on your website has adequately prepared me for this semester and I expect to have success. Thank you for providing these resources for students such as myself. There's no way that I could feel as confident going into this semester without having gone through the training that you provided. Thank you for all that you and your team does. I wish you all the best.

I'm a 40 year old going back to college at Penn State online to finish my business degree. I have not taken a math class in 20 years and when I found out that I had to take the Aleks test, I researched tutorials online. Out of the many tutorials that I sampled before I purchased, mathhelp.com was the best at providing short lessons that were to the point. I finally understand Algebra because of these lessons. I took the Aleks test this week and scored high enough to place me into Algebra II.After Algebra II, my only other math class will be Calculus. That was my goal and I accomplished it. I do plan on using mathhelp.com again when I start Algebra II in the spring semester and also when I take Calculus. Because of this tutorial, I am no longer terrified of math!

Mathhelp.com was extremely helpful. I increased my math placement test score by 135 points by using the website. I am now ready to take college algebra. The teachings are a good pace and the most helpful thing are the links to previous lessons that remind you of building blocks you need for the current lesson. Also, the option to have the audio of a problem on the practice problems is extremely helpful.

Wanted to say thanks so much for putting together the Mathhelp curriculum for people like me. Without all the content I would not have been successful on the TSI placement test. The most helpful was definitely the factoring, exponent rules and fractions involving radicals since you see a lot of that on the test. Overall it was very easy to learn and follow and built my confidence up and helped me be successful. I scored a 350 out of a possible 390 according to my advisor and now I’m in my second week of college algebra on a summer mini semester! Thanks to all of you and keep up the good work. I made a suggestion to my school that they should recommend your site to people like me as a prep for the placement test.

I have been out of high school for 30+ years and am going to take a few college courses. I took a practice Accuplacer test and realized that I did not remember hardly any of my high school math so I took the Accuplacer College Level Math prep course. I placed past College Algebra and into Trig with the help of the course.

The PRAXIS Algebra 1 test went very well! I received a passing score of 154, which was 13 points higher than when I took it previously. The lessons that were most beneficial to me were the problems focusing on deciphering word problems, imaginary numbers, and functions. These were the areas I had struggled with previously. I absolutely LOVED how the lessons built off one another and worked together as a whole. Also, thank you for providing links to previous lessons in order to build further background knowledge. I have recommended your program to many fellow teachers. Thank you!

I took and passed the math TSI exam on my first attempt. I am a 35 year old that hasn’t used formulas, geometry, algebra or any other advanced math since high school. The TSI prep that y’all offered was better than any YouTube or practice test I had tried. I think you guys have got the best tool on the market. I used it as an all-around refresher and was able to have the confidence I needed to excel with the test. The way it was broken up into lessons, videos, practice and quizzes gives the student the ability to pick and choose exactly what they need help with.

Excellent math program! I'm learning along with my kids since I only took Algebra I and Geometry and that was decades ago (I'm an English teacher, not a math teacher!). We can fast forward or review lessons to go at a pace that's just right. The explanations are clear and precise. Having the ability to move between courses is the best part -- Algebra one day and Geometry the next.

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

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.
