Notes
The examples on the transparency
masters assume all default settings.
The transparency master showing the
Equation Operating System (EOSé)
demonstrates the order in which the
TI-34 Û 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 x 3 = 7
(1 + 2) x 3 = 9
