    Column by column: 402 + 19

    • Ones: 2 + 9 = 11 — write 1, carry 1.
    • Tens: 0 + 1 + 1 = 2 — write 2.
    • Hundreds: nothing to add — write 4.

    402 + 19 = 421

    Second check: 421 − 402 = 19

    FAQ

    What is 402 + 19?

    402 + 19 = 421

    How do you check that 402 + 19 = 421?

    Subtract one addend from the sum: 421 − 19 = 402, and 421 − 402 = 19. Getting the other addend back means the sum is right.

    How many carries are there in 402 + 19?

    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 19 + 402 the same as 402 + 19?

    Yes. Addition is commutative, so both give 421; the column looks the same with either number on top.
