    Column by column: 864 + 36

    • Ones: 4 + 6 = 10 — write 0, carry 1.
    • Tens: 6 + 3 + 1 = 10 — write 0, carry 1.
    • Hundreds: 8 + 1 = 9 — write 9.

    864 + 36 = 900

    Second check: 900 − 864 = 36

    FAQ

    What is 864 + 36?

    864 + 36 = 900

    How do you check that 864 + 36 = 900?

    Subtract one addend from the sum: 900 − 36 = 864, and 900 − 864 = 36. Getting the other addend back means the sum is right.

    How many carries are there in 864 + 36?

    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 36 + 864 the same as 864 + 36?

    Yes. Addition is commutative, so both give 900; the column looks the same with either number on top.
