Casio FX-82ES PLUS User Manual

9 Multiplication (×), division (÷)
10 Addition (+), subtraction (-)
Note
• When squaring a negative value (such as -2), the value being squared must be
enclosed in parentheses (
2 ). Since x
2
has a higher priority than
the negative sign, inputting 2 would result in the squaring of 2 and then
appending a negative sign to the result.
• Always keep the priority sequence in mind, and enclose negative values in
parentheses when required.
