Peter sed:
Decimal is only important for people who use their fingers to count.

or anytime you communicate with that small minority of people in the world ( 6,379,038,183 out of 6,443,472,913, as a SWAG) who don't use alternative number bases on a regular basis...

what the heck does 3 mean if you're adding them in binary?
11 + 111 = 1010 in binary. 3 doesn't exist to be added in the binary system.

Yes it does....
11(base 2) = 3(base 10)
111(base 2) = 7(base 10)
so 11(base 2) +111(base 2) = 1010(base 2)
