WebIn cryptography, we use A=0 ... Z=25. This makes sense, because if a shift is 0 you can assume that the letters were shifted by 0, which means they were shifted by nothing. Any letter shifted by 0 is that letter. Think of it like addition: you are adding a number. Any number + 0 is that number, therefore A+0 is A, right?
