Calculation Priority Sequence - Casio fx-92B User Manual

1
* Input of the closing parenthesis is required for sin, sinh, and other functions
that include parentheses.
2
* These multiplication symbols ( ) can be omitted. A multiplication symbol
can be omitted when it occurs immediately before an opening parenthesis,
immediately before sin or other function that includes parentheses,
immediately before the Ran# (random number) function, or immediately
before a variable (A, B, C, D, E, F, M, X, Y),

Note: • If the calculation becomes longer than the screen width during
input, the screen will scroll automatically to the right and the
appear on the display. When this happens, you can scroll back to the left by
using and
pressing will cause the cursor to jump to the beginning of the calculation,
while will jump to the end. • When Natural Display is selected, pressing
while the cursor is at the end of the input calculation will cause it to jump
to the beginning, while pressing
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 10 bytes. • The cursor will change shape to
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.
