Calculation Priority Sequence - Casio FX-115ES PLUS User Manual

e while the cursor is at the end of the input calculation will cause it to jump
to the beginning, while pressing d while the cursor is at the beginning will
cause it to jump to the end. • You can input up to 99 bytes for a calculation.
Each numeral, symbol, or function normally uses one byte. Some functions
require three to 13 bytes. • The cursor will change shape to k when there are
10 bytes or less of allowed input remaining. If this happens, end calculation
input and then press =.

Calculation Priority Sequence

The priority sequence of input calculations is evaluated in accordance with the
rules below. When the priority of two expressions is the same, the calculation
is performed from left to right.
1st
Parenthetical expressions
Functions that require an argument to the right and a closing
2nd
parenthesis ")" following the argument.
Functions that come after the input value (
3rd
%, '
t
), powers (
4th
Fractions
Negative sign (–), base-
Note: When squaring a negative value (such as –2), the value
being squared must be enclosed in parentheses ((- 2 )w
=). Since
5th
inputting - 2 w= 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.

7th Multiplication where the multiplication sign is omitted

10th Multiplication (×), division (÷), remainder calculations (÷R)
11th Addition, subtraction (+, –)

Inputting with Natural Display
Selecting Natural Display makes it possible to input and display fractions
and certain functions (log,
Abs) just as they are written in your textbook.
