Why is 1 % 2 = 1? I understand that 13 % 4 = 1 because 1 is the remainder of 13 / 4, but I don't see how the first modulus works. Can someone explain this please?

I really do not understand the "property" and the "setter". The "property" makes the attribute read-only, but the "setter" makes the attribute mutable. So if we want to use "property", why we need to introduce the "setter".
