Order of operations and parentheses
Keys
1. D opens a parenthetical expression.
2. E closes a parenthetical expression.
Notes
The examples on the transparency
masters assume all default settings.
The transparency master showing the
Equation Operating System (EOS™)
demonstrates the order in which the
TI-34 MultiView™ calculator completes
calculations.
Operations inside parentheses are
performed first. Use D E to change the
order of operations and, therefore,
change the result.
Example: 1 + 2 × 3 = 7
(1 + 2) × 3 = 9
