How do you confuse calculator?

If you get a number greater than 9, add the digits up again. For example, if the number is 34291 , we add the digits up (3 + 4 + 2 + 9 + 1) and get 19 ; add those digits (1 + 9) and get 10 ; add those digits (1 + 0) and get 1 ; so the remainder when dividing by 9 would be 1.

### How do calculators know all the answers?

Calculators (and computers) combine inputs using electronic components called logic gates. As the name implies, a logic gate acts as a barrier in an electronic circuit; it takes in two electric currents, compares them and sends out a new current based on what it finds.
