2/Order Of Operations And Levels - Casio FX-180PA Manual

®Perform the following calculation:
1 ®2O0Ø
(å` Look at the display to see what the current lower limit is.
If the display reads:
5. 03, the current setting is Type A
If the display reads:
0.005, the current setting is Type B
5-
03
0.005
g; Press
to switch between the Type A and Type B lower limits
'Note that the lower limit is not changed if you press ®0
while the number of signifi-
cant digits (SCI displayed) and/or the number of decimal places (FIX displayed) are speci-
fied. The first time you press ®Qa , you clear the FIX and SCI specifications, and so
you must press again to change the lower limit.
2/ORDER OF OPERATIONS AND LEVELS
Operations are performed in the following order of precedence:
1. Functions
2. x", x',, R- P, P -R, nPr, nCr
3. x, -
4. +, -
5. AND
6. OR, XOR, XNOR
BASE -N mode
Operations with the same precedence are performed from left to right, with operations
enclosed in parentheses performed first. tf parentheses are nested, the operations en-
closed in the innermost set of parentheses are performed first.
Registers L, through L 6 are provided to store operations of lower precedence (includ-
ing parenthetical operations). Since six registers are provided, calculations up to six lev-
els can be retained.
Since each level can contain up to three open parentheses, parantheses can be nested
up to 18 times.
Ex.) (4 levels, 5 nested parentheses)
