Would someone please explain to me the following sentence (taken from the book, Chapter 1):

The If-x-then-y function (also known as x -> y, or ‘‘x Implies y’’) returns 1 when x is
0 or when both x and y are 1.

I *never* understood "X Implies Y". I mean, "False Implies True"?

Can somebody break it down for me please?
