The TI-83 series of powerful handheld calculators made by Texas Instruments includes the TI-83 Plus. It can work advanced equations by using computing power made specifically for mathematical problem-solving. The TI-83 is a capable calculator, but Texas Instruments also has upgraded models such as the TI-84 and TI-85. You can perform a cubed root equation on all of the models using a similar process. Doing a cube root graphing calculator equation is fairly consistent across the board.

## Understanding Cubed

Before you jump into the cube root equation and perform the calculation on a TI-83, understanding the function of a cube is prudent. The cubed equation multiples a number to the third power or "n3." To do this, you multiply the number by itself two times. If your number is 5 cubed, you use 5x5x5 to reach the third power, which is 125, in this case. That means the cube root of 125 is 5. When you have a cube in geometry and want to find the volume of the cube, the same equation applies. All sides of the cube are identical and calculating n to the third power determines the volume.
