    FAQ

    What is 402 + 149?

    402 + 149 = 551

    How do you check that 402 + 149 = 551?

    Subtract one addend from the sum: 551 − 149 = 402, and 551 − 402 = 149. Getting the other addend back means the sum is right.

    How many carries are there in 402 + 149?

    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 149 + 402 the same as 402 + 149?

    Yes. Addition is commutative, so both give 551; the column looks the same with either number on top.
