    FAQ

    What is 78 + 19?

    78 + 19 = 97

    How do you check that 78 + 19 = 97?

    Subtract one addend from the sum: 97 − 19 = 78, and 97 − 78 = 19. Getting the other addend back means the sum is right.

    How many carries are there in 78 + 19?

    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 19 + 78 the same as 78 + 19?

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