AOS™ (Algebraic Operating System) Calculations

When you select the AOS calculation method, the calculator uses the standard rules of algebraic hierarchy to determine the order in which it performs operations.

Algebraic Hierarchy

The table shows the order in which the calculator performs operations using the AOS calculation method.
