0 and 1

You would expect that all of the 10 digits can be handles in the same way. But that is not the case.



The numbers 0 and 1 have special meanings, and when using them in calculations you must pay special attention. In primary school you may have noticed this already. The multipiclation table for 0 was excluded, because every number multiplied by 0 gives 0. It disappears. The table for 1 was easy, as every number multiplied by 1 stays unchanged. But that is just amazing.

A computer uses internally only zeroes and ones, so works binary. It is all about the opposites, like: on and off, black and white, light and dark, thing or nothing, one or none, etc.

It are both very important numbers. So keep in mind
