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 (2
π
, 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(2
π
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)).
