Basic Calculations

Calculation Priority Sequence

Your ClassPad automatically performs calculations in the following sequence.

1Commands 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.)

Command with parentheses multiplication operations that omit the multiplication sign (2 3, etc.)

⋅, ÷

5+, –, (–)

6Relational operators (=, ≠, <, >, <, >) 7and

8or, xor

9with ( )

Example: 2 + 3 ⋅ (log (sin(2π2)) + 6.8) = 22.07101691 (In Algebra mode, Decimal mode,

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 4through 9that 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)).
