Question

Bobby subtracted 75 - 45 and said the answer is 30. Is his answer reasonable? why or why not?
Ms. Sue
It looks reasonable to me.

7 - 4 = 3
5 - 5 = 0

Reiny
I don't understand the question.
Is the answer reasonable?
30 is the answer.
Sarah
It looks reasonable to me because 75-45= 30 and 30+45= 75
Nicole
His answer is reasonable because
75-30=45 and 45+30=75.
