    What is 85 + 54?

    Answer

    85 + 54 =
    139

    The sum is longer than the addends: 1 carry — into the hundreds; the last one makes a new digit

    85 + 54 in a column. Carries are the small circled digits above the columns.
    1carry
    8 5
    +54
    139

    Column by column: 85 + 54

    • Ones: 5 + 4 = 9 — write 9.
    • Tens: 8 + 5 = 13 — write 3, carry 1.
    • Hundreds: the carried 1 — write 1.

    85 + 54 = 139

    Second check: 139 − 85 = 54

    FAQ

    What is 85 + 54?

    85 + 54 = 139

    How do you check that 85 + 54 = 139?

    Subtract one addend from the sum: 139 − 54 = 85, and 139 − 85 = 54. Getting the other addend back means the sum is right.

    How many carries are there in 85 + 54?

    1 carry: 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 54 + 85 the same as 85 + 54?

    Yes. Addition is commutative, so both give 139; the column looks the same with either number on top.
