Students learn how to solve problems using a log calculator. For example, the value of log 47 can be found by entering '47 log' into a scientific calculator. On a graphing calculator, however, students simply enter 'log 47.' Both types of calculators serve as log calculators. Students also learn to use the inverse log (or 2nd log) button on a log calculator to find the value of x in a problem like the following: log x = 0.581. Finally, students are asked to round their answers to log calculator problems to the nearest thousandth.
