These examples show angles in degrees. Chapter 1: Overview of Calculator Operations 7 More on Selected Math Operations Universal Power The key lets you raise a positive number to any power. However, you can raise a negative number to an integer power or the reciprocal of an odd number only. In either case, the power can be either positive or negative. Parentheses Parentheses let you control the order in which a numeric expression is evaluated. The portion of an expression enclosed in parentheses is evaluated separately. Up to 15 levels of parentheses are available, with up to 8 pending operations. If an expression ends in a series of closed parentheses, you can press to close all of the parentheses, evaluate the expression, and display the end result. To see intermediate results, press repeatedly. Factorial To calculate the factorial of a displayed number, press must be a positive integer 69. .
