In this activity the computer makes up a mystery operation, and you have to figure out what the operation is. You give the computer two numbers to calculate, and it tells you the answer. This is your first piece of evidence. Need another clue? Then gather more evidence. Keep entering pairs of numbers for the computer to calculate until you think you know what's going on. When you have an idea of how the operation works, select Test Me. The computer will give you an operation, and you can try your wit at solving the mystery.

To start, type a number in each of the boxes below. Then press Calculate.

Computer, what is? ?
