well, the shortest answer is : the do maths very well, thanks for asking.

the more helpful answer is that the rules for binary are basically the same, its just a different annotation system. 1010 and ten are the same value, expressed differently. adding 1 to them still gets you to eleven, even if its written as 1011. doubling that figure gets you to twenty two/10110, etc, etc.

computers tend to do the same basic math, just REALY REALLY FAST. that lets then do complex math fast, which in turn lets them do…well. everything they do.
