I don't seem to be able to find a clear answer to this question on the internet. My maths teacher today said that (simplified): b=0 => 0=0 where you multiplied with 0 on both sides. I thought that b=0 <=> 0=0 , but can't explain why, and don't know which is correct, because I don't know, exactly, what the signs mean.
