    FAQ

    What is 105 + 67?

    105 + 67 = 172

    How do you check that 105 + 67 = 172?

    Subtract one addend from the sum: 172 − 67 = 105, and 172 − 105 = 67. Getting the other addend back means the sum is right.

    How many carries are there in 105 + 67?

    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 67 + 105 the same as 105 + 67?

    Yes. Addition is commutative, so both give 172; the column looks the same with either number on top.
