How do you check that 136 + 15 = 151?

Subtract one addend from the sum: 151 − 15 = 136, and 151 − 136 = 15. Getting the other addend back means the sum is right.

How many carries are there in 136 + 15?

1 carry: every time a column added up to 10 or more, its ones digit was written and 1 was carried to the next column on the left.

Is 15 + 136 the same as 136 + 15?

Yes. Addition is commutative, so both give 151; the column looks the same with either number on top.
