Calculation Priority Sequence
Your ClassPad automatically performs calculations in the following sequence.
Commands with parentheses (sin(, diff(, etc.)
Factorials (
x
!
), degree specifications (
o
,
r
), percents (%)
Powers
P
, memory, and variable multiplication operations that omit the multiplication sign (2
P
, 5A,
etc.)
Command with parentheses multiplication operations that omit the multiplication sign (2 3,
etc.)
s
, ÷
+, –, (–)
Relational operators (=,
x
, <, >,
,
)
and
or, xor
with ( | )
Example:
2 + 3
s
(log (sin(2
P
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
through
that are the same priority sequence level, the same level operations are
performed from left to right. A series of power calculations
(example: 5^2^3) is performed from
right to left (5^(2^3)).
