    • Tens: 4 + 8 + 1 = 13 — write 3, carry 1.
    • Hundreds: 6 + 4 + 1 = 11 — write 1, carry 1.
    • Thousands: the carried 1 — write 1.

    647 + 485 = 1,132

    FAQ

    What is 647 + 485?

    647 + 485 = 1,132

    How do you check that 647 + 485 = 1,132?

    Subtract one addend from the sum: 1,132 − 485 = 647, and 1,132 − 647 = 485. Getting the other addend back means the sum is right.

    How many carries are there in 647 + 485?

    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 485 + 647 the same as 647 + 485?

    Yes. Addition is commutative, so both give 1,132; the column looks the same with either number on top.
