Basic Calculations

Calculation Priority Sequence

Your ClassPad automatically performs calculations in the following sequence. 1 Commands with parentheses (sin(, diff(, etc.)

2Factorials (x!), degree specifications (o, r ), percents (%)

3Powers

4π, memory, and variable multiplication operations that omit the multiplication sign (2π, 5A, etc.)

Tip

•Expressions in parentheses are given priority.

•In cases where a series of calculations in the same expression includes more than one of the operators 4 through 9 that are the same priority sequence level, the same level operations are performed from left to right. A series of power calculations 3 (example: 5^2^3) is performed from right to left (5^(2^3)).
