Can you disprove this please?

Question

"the difference of any two whole numbers is always a whole number"

i know you can disprove it cuz im supposed to find how in my homework its just that i cant think of what it could be! (i think that whole numbers are all counting numbers, both positive and negative, right?)

Answer 1

It will be something lame, like "the difference between 5 and 5 is 0, which is not a whole number." Something stupid like that.

Answer 2

whole numbers are numbers 0-infinity.

they are only positive.

and its not true because you could disprove it by saying 2-3.

because that = -1 and -1 is not a whole number.

hope i helped and please pick me as best answer since i answered first and we just reviewed whole numbers monday.
