Arithmetic Operations

The four basic arithmetic operations - addition, subtraction, multiplication, and division - are the mathematical functions you will use most often when solving problems with your calculator.


Basic Arithmetic Keys

The [ + ], [ - ], [ × ], and [ ÷ ] keys perform the four basic arithmetic functions. When you use a combination of these functions in an expression, the AOS™ system keeps track of the priorities and causes the functions to be performed in the correct order.
The [ = ] key completes all pending operations and displays the result of a calculation.

Example

Calculate 15 + ( 6 ÷ 3 ) × 4.
