FX 300 MS Training guide Basic Arithmetic Calculations Making Corrections During Input • Use the left and right arrows on the REPLAY function to move the cursor to the location you want to correct. • Press [DEL] to delete at the current cursor position • Press [SHIFT] [INS] to change the cursor to an insert cursor [ ]. Replay Function 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). Notes: Replay memory capacity is 128 bytes. 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] [=] . Order of Operations The calculator uses "order of operations". Examples: 2 + 3 x 4 = 14 You do not need parentheses around 3 x 4. (2 + 3) x 4 = 20 Use Replay and [SHIFT] [INS] to add parentheses. Blinking [ ] is the insert cursor. -22= -4 (- 2) 2 = 4 Display Format 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). Scientific Notation: Press 2: SCI You will then be prompted for the number of significant digits (0 - 9). Normal Notation: Press 3: NORM You will then be prompted for NORM 1 or NORM 2. NORM 1 uses exponential notation for integers with more than 10 digits and decimal values with more than 2 decimal places. Ex/ 1 ÷ 1000 = 1 x 10-3 NORM 2 uses exponential notation for integers with more than 10 digits and decimal values with more than 9 decimal places. Ex/ 1 ÷ 1000 = .001 2 References the Casio FX-300 MS User's Guide Casio FX-300MS Scientific calculator
