As you progress into more and more advanced math classes, you will need more advanced equipment, such as the TI 83 calculator. The calculator, made by Texas Instruments, is a graphing calculator that not only can be used to perform basic calculations, but also to map out graphs on the large display screen as well. One of the other features the TI 83 calculator can do is add, subtract, multiply or divide fractions together.

Power on the calculator by pressing the yellow button on the upper right side of the calculator, directly below the screen and above the arrow keys.

Look at the math problem you need to solve. You will punch in the problem almost exactly as it is written. If the question asks you to add 1/4 and 12/17 together you will need to place curved brackets around each fraction. In other words, type the question in the TI 83 calculator to look like (1/4) + (12/17). The slanted line in between the one and four and the 12 and 17 is the divide button.
