Casio fx-82CW - Calculation Priority Sequence

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
2
Functions that have parentheses (sin(, log(, f(, g(, etc.,
functions that take an argument to the right, functions that
require a closing parenthesis after the argument)
3
Functions that come after the input value (x
2
, x
-1
, x!, °’ ”, °,
r
,
g
, %), powers ( ), roots ( )
4 Fractions
5 Negative sign ((-))
6
Statistics app estimated values (xˆ, yˆ, xˆ
1
, xˆ
2
)
7 Multiplication where the multiplication sign is omitted
8
Permutation (nPr), combination (nCr)
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)
2
. This is because x
2
is a function
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
2
= -4
((-))2 (-2)
2
= 4
