Calculation Priority Sequence - Casio fx-82CW User Manual

Calculation Priority Sequence

The calculator performs calculations according to a calculation priority
sequence.
• Basically, calculations are performed from left to right.
• Expressions within parentheses have the highest priority.
• The following shows the priority sequence for each individual command.
1 Parenthetical expressions
Functions that have parentheses (sin(, log(, f(, g(, etc.,
2 functions that take an argument to the right, functions that
require a closing parenthesis after the argument)
Functions that come after the input value (x

, %), powers (
4 Fractions
5 Negative sign ((-))
6 Statistics app estimated values (x ˆ , y ˆ , x ˆ
7 Multiplication where the multiplication sign is omitted
Permutation (nPr), combination (nCr)
8
9 Multiplication (×), division (÷)
10 Addition (+), subtraction (−)
If a calculation contains a negative value, you may need to enclose
the negative value in parentheses. If you want to square the value -2,
for example, you need to input: (-2)
preceded by a value (Priority 3, above), whose priority is greater than the
negative sign, which is a prefix symbol (Priority 5).
Example:
((-))2 -2
