    FAQ

    What is 36 + 15?

    36 + 15 = 51

    How do you check that 36 + 15 = 51?

    Subtract one addend from the sum: 51 − 15 = 36, and 51 − 36 = 15. Getting the other addend back means the sum is right.

    How many carries are there in 36 + 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 + 36 the same as 36 + 15?

    Yes. Addition is commutative, so both give 51; the column looks the same with either number on top.
