Question

Is the following always, sometimes, or never true?m + 0 = 0

Answer 1

anything added to 0 is the number itself
i.e
0 + 0 = 0
1 + 0 = 1
2 + 0 = 2
3 + 0 = 3
and so on

Answer 2

so if m is 0, what would m+0 be? and if m is something else, say 4, what would m+0 be? Answer those questions and you should be able to figure out the correct response.
