BU537 Lecture Notes - Lecture 12: Elementary Arithmetic, Scientific Notation, Decimal Mark
Document Summary
Every time you perform a calculation, the replay function stores the calculation formula and its result in replay memory. Pressing the up arrow displays the formula and result of the calculation you last performed. If you continue to press the up arrow, you will scroll sequentially through your last calculations (most recent to oldest). Pressing ac will not clear the replay memory. If you want to clear the replay memory, press the on key or reset the modes/settings: Press [shift] [clr] [2] [=] or [shift] [clr] [3] [=] . Examples: 2 + 3 x 4 = 14 (2 + 3) x 4 = 20. You do not need parentheses around 3 x 4. Use replay and [shift] [ins] to add parentheses. To change the exponential display format, press the [mode] key 3 times. Fixed number of decimal places: press 1: fix. You will then be prompted for the number of decimal places (0 9).
