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)).
