i cant understand how it works:
i have two bit numbers (x1 x0 ,y1 y0) which are needed to be subtruction
i cant understand why
x1 x0 y1 y0 | B D1 D2
0 0 0 1 | 1 1 0
0 0 1 0 | 1 0 1
0 0 1 1 | X X X
i cant understand these arithmetics
the first one is 0-1=-1
so in base 3 the resolt is should be three but i cant understand what meen Borrow=1
and the resolt 10
i dont understand how did they desided that
and why we have dont cares on the third example
