MATH = fractions to/from decimals, cube, cube root, xth root, min/max, etc.

NUM = absolute value, LCM, greatest common denominator

CPX = complex number calculations

PRB = probability (random numbers, permutations, combinations, etc.)

***Find the cubed root of 4, 913. ___________

***Find the LCM of 72 and 44. ___________

***List TEN random numbers given. _________________________________

[2nd] [0] will access the CATALOG menu on the screen.

This is a ABC listing of all processes available for you to use on the calculator.

Move the cursor by using directional keys[↑][↓][←][→].

Once you find the process you wish to use, press [ENTER].
