This is a normal post it's more to do with nature of binary itself, which goes up by two with each full column
so 7 (binary: 111) x 5 is the same as multiplying by (2,2,2,1)(adding 2x5 + 2x5 + 2x5 and itself together). The column format and rounding down give you a nice way of rationalising this. So 2,2,2,1 becomes 4,2,1. 6 Binary (110) becomes 4,2,0. 10 (binary 1010) 8,0,2,0 instead of 2,2,2,2,2

This is a normal post 7 is 111 in binary. Not 1111. That's 15.
6 is 110 and 10 is 1010.
So. Err.

This is a normal post fucksocks. i realised I'd made an error but pasted over the wrong bit
still, the proof is solid. multiplying something by a binary value means adding double the value with every column, as the binary column represents 2. So his method is breaking one of the factors up into twos (converting to binary), with a handy method of rationalising this.
