    Column by column: 647 + 453

    • Ones: 7 + 3 = 10 — write 0, carry 1.
    • Tens: 4 + 5 + 1 = 10 — write 0, carry 1.
    • Hundreds: 6 + 4 + 1 = 11 — write 1, carry 1.
    • Thousands: the carried 1 — write 1.

    647 + 453 = 1,100

    Second check: 1,100 − 647 = 453

    FAQ

    What is 647 + 453?

    647 + 453 = 1,100

    How do you check that 647 + 453 = 1,100?

    Subtract one addend from the sum: 1,100 − 453 = 647, and 1,100 − 647 = 453. Getting the other addend back means the sum is right.

    How many carries are there in 647 + 453?

    3 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 453 + 647 the same as 647 + 453?

    Yes. Addition is commutative, so both give 1,100; the column looks the same with either number on top.
