Calculation Priority Sequence
Your ClassPad automatically performs calculations in the following sequence.
1 Commands with parentheses (sin(, diff(, etc.)
2 Factorials (x!), degree specifications (
o
,
r
), percents (%)
3 Powers
4 π, 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 +, –, (–)
6 Relational operators (=, ≠, <, >, <, >)
7 and
8 or, xor
9 with ( | )
Example: 2 + 3 × (log (sin(2π
2
)) + 6.8) = 22.07101691 (In Algebra mode, Decimal mode,
Radian 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 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)).
