It uses math and it uses 0. When you use 0 in math everything becomes 0 after you multiply it. The more you multiply the more 0 it becomes. I bet you have to multiply a lot in cryptography.
Math is about precision, so it's generally not a good idea to have something become "more 0" than actually needed. Especially in cryptography.
So here's my advice. If you multiplied too much by zero, you can make it less 0 by dividing a few times by zero. Then maths would be closer to the precise 0 that you were looking for in the first place.
