    • Tens: 7 + 6 + 1 = 14 — write 4, carry 1.
    • Hundreds: 5 + 4 + 1 = 10 — write 0, carry 1.
    • Thousands: the carried 1 — write 1.

    578 + 468 = 1,046

    Second check: 1,046 − 578 = 468

    FAQ

    What is 578 + 468?

    578 + 468 = 1,046

    How do you check that 578 + 468 = 1,046?

    Subtract one addend from the sum: 1,046 − 468 = 578, and 1,046 − 578 = 468. Getting the other addend back means the sum is right.

    How many carries are there in 578 + 468?

    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 468 + 578 the same as 578 + 468?

    Yes. Addition is commutative, so both give 1,046; the column looks the same with either number on top.
