# Basic Equations

Equations are entered in standard mathematical form. For example to add 7 and 2 enter the following:

7+2

To solve, press the = button with your mouse or the Enter key on your keyboard.

Calculations are performed in mathematical order - multiplication and division are performed before addition and subtraction. The following equation solves to 1 (3×2 = 6, 7−6 = 1).

7−3×2

To change the order of calculation use parenthesis. The following equation solves to 8 (7−3 = 4, 4×2 = 8).

(7−3)×2
