    FAQ

    What is 172 + 149?

    172 + 149 = 321

    How do you check that 172 + 149 = 321?

    Subtract one addend from the sum: 321 − 149 = 172, and 321 − 172 = 149. Getting the other addend back means the sum is right.

    How many carries are there in 172 + 149?

    2 carries: 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 + 172 the same as 172 + 149?

    Yes. Addition is commutative, so both give 321; the column looks the same with either number on top.
