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 completes calculations. 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

The examples on the transparency masters assume all default settings. Enter the operation (any combination of numbers, operators, or menu items and their arguments). The TI-34 automatically calculates the result and displays the counter on the left side of the result line. (You do not have to press <. ) You can set the TI-34 to display only the counter and the result (excluding the entry). Repeat to toggle this setting off.
