Think I've got,
zero divided by any integer is zero, but since zero is also an integer then it holds.
Am I right?
Hi all,
I am given two relations and asked to prove which one is an equivilence relation for integers.
They are;
~ if is divisible by 5.
~ if is divisible by 4.
The problem i'm having is finding which one has reflexivity.
for example, which is not divisble by 5.
and, for all
So, is zero divisible by 4?
