Instructions for a Casio MS-80VER

The Casio brand has been at the forefront of desktop calculators since the electronic era stepped into the "Calculator Wars" back in the early 1960s. Casio was a driving force in the market then and continues to thrive today. The MS-80VER model is a good example of a simple yet very useful calculator.

Basic operations

• 1

  Key in a number, press the add (+) button and key in another number. Continue until you've keyed in the final number and press the equals (=) button to get the sum of a series of numbers. Note that every time you press the add (+) button, you will see a subtotal of the previously entered numbers on the display.

• 2

  Enter a number and press the subtract (-) button, enter another number and the calculator will perform a subtraction operation. It works just as the addition feature in that it displays a subtotal of all numbers previously subtracted. Hit the equals (=) button to get the final result of your calculation.

• 3

  Multiply two or more numbers simply by pressing the multiply (x) button after entering each number. To get the final result press equals (=). The division function works in the same manner using the division symbol key (÷), instead of the multiply key.

• 4

  Calculate percentages easily by using the percentage feature. For example to get 30 percent of 1000, simply enter 1000 then press multiply (x), key in 30 and press percent (%).

• 5

  Press the "AC" or "C" button to clear the entry if you made a mistake while performing a calculation.
