    FAQ

    What is 172 + 34?

    172 + 34 = 206

    How do you check that 172 + 34 = 206?

    Subtract one addend from the sum: 206 − 34 = 172, and 206 − 172 = 34. Getting the other addend back means the sum is right.

    How many carries are there in 172 + 34?

    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 34 + 172 the same as 172 + 34?

    Yes. Addition is commutative, so both give 206; the column looks the same with either number on top.
