Why does my calculator keep giving the wrong answers?

Answer 1

You should first experiment with the calculator by having a friend or relative work a

few problems with it, and observe whether the accuracy of the results is a function

of the machine itself or of the operator. If the accuracy varies with different operators,

then we can conclude that your calculator shares a well-known, exhaustively-documented

characteristic with all machines designed for human input or control. The characteristic is

referred to by mathematicians, physicists, engineers, and stenographers by the official

SI acronym: GIGO. The acronym stands for the phrase "Garbage In, Garbage Out".
