i don't understand the question... What do you mean by 'convert 1 into 0'?

if you are trying to convert it into a decimal number, each position represents a power of 2, just like decimal each position is a power of 10.

So the rightmost digit is 2^0, the next is 2^1, the next is 2^2, etc. you just add up the values where there is a 1. so if i had a four digit binary like "0111", i'd add up 2^0 + 2^1 + 2^2, which totals 7.

Does that help?

There are only two hard things in computer science: cache invalidation, naming things, and off-by-one errors
