    How do you check that 3,579 + 1,234 = 4,813?

    Subtract one addend from the sum: 4,813 − 1,234 = 3,579, and 4,813 − 3,579 = 1,234. Getting the other addend back means the sum is right.

    How many carries are there in 3,579 + 1,234?

    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 1,234 + 3,579 the same as 3,579 + 1,234?
