    Column by column: 54 + 15

    • Ones: 4 + 5 = 9 — write 9.
    • Tens: 5 + 1 = 6 — write 6.

    54 + 15 = 69

    FAQ

    What is 54 + 15?

    54 + 15 = 69

    How do you check that 54 + 15 = 69?

    Subtract one addend from the sum: 69 − 15 = 54, and 69 − 54 = 15. Getting the other addend back means the sum is right.

    How many carries are there in 54 + 15?

    None: no column adds up to 10 or more, so every digit of the sum is written straight away.

    Is 15 + 54 the same as 54 + 15?

    Yes. Addition is commutative, so both give 69; the column looks the same with either number on top.
