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.

It are both very important numbers. So keep in mind
