The transparency master showing the Equation Operating System (EOSé) demonstrates the order in which the TI-34 Û completes calculations. Use D E to change the order of operations and, therefore, change the result.

Enter the operation (any combination of numbers, operators, or menu items and their arguments). The TI-34 Û 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 Û to display only the counter and the result (excluding the entry). [. . . ] In statistics, n = 1.
