Math::NoCarry - Perl extension for no- carry arithmetic River stage one • 1 direct dependent • 1 total dependent

No-carry arithmetic doesn't allow you to carry digits to the next column. For example, if you add 8 and 4, you normally expect the answer to be 12, but that 1 digit is a carry. In no-carry arithmetic you can't do that, so the sum of 8 and 4 is just 2...
