    FAQ

    What is 45 + 19?

    45 + 19 = 64

    How do you check that 45 + 19 = 64?

    Subtract one addend from the sum: 64 − 19 = 45, and 64 − 45 = 19. Getting the other addend back means the sum is right.

    How many carries are there in 45 + 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 + 45 the same as 45 + 19?

    Yes. Addition is commutative, so both give 64; the column looks the same with either number on top.
