    FAQ

    What is 268 + 128?

    268 + 128 = 396

    How do you check that 268 + 128 = 396?

    Subtract one addend from the sum: 396 − 128 = 268, and 396 − 268 = 128. Getting the other addend back means the sum is right.

    How many carries are there in 268 + 128?

    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 128 + 268 the same as 268 + 128?

    Yes. Addition is commutative, so both give 396; the column looks the same with either number on top.
