Sophia and Benjamin have been asked
to solve 96 subtract 45. Sophia solves it and gets an answer
of 51. Benjamin solves it and gets an
answer of 31. Who is correct? Use the vertical column method to
find out. Check your answer using the inverse
operation. What number do you add to 45 to get
96?

First, we need to find the answer
to 96 take away 45. Six take away five is one, and nine
take away four is five. So the answer is 51. So who was correct, Sophia or
Benjamin? Sophia said 51, so she’s
correct.

Now we need to check Sophia’s
answer using the inverse operation. In other words, what do we add to
45 to get 96? The question is asking us to check
if 45 and 51 make 96. Five plus one makes six; four plus
five makes nine. So we add 51 to 45 to make 96.

Sophia was correct to say that 96
take away 45 is 51. And we checked her answer using the
inverse operation and found that you need to add 51 to 45 to make 96.
