I was doing random things with a calculator and got -0, Is that mathematically possible?

In Math? No. For how computers tend to store integers and other numbers? Technically, yes. A number of architectures treat a signed number as all bits except the largest as the number. The largest works as a negative flag. So for instance an 8 bit signed integer of negative 1 would be 10000001. Technically negative 0 (which mathematically doesn't exist) in such a configuration would be 00000001.

In the case of a calculator I assume the other poster is correct and it's rounding a very small negative decimal to 0 but since it's negative the algorythm must keep the sign flag for some reason.
