How do you check that 85 + 12 = 97?

Subtract one addend from the sum: 97 − 12 = 85, and 97 − 85 = 12. Getting the other addend back means the sum is right.

How many carries are there in 85 + 12?

None: no column adds up to 10 or more, so every digit of the sum is written straight away.

Is 12 + 85 the same as 85 + 12?

Yes. Addition is commutative, so both give 97; the column looks the same with either number on top.
