    FAQ

    What is 354 + 307?

    354 + 307 = 661

    How do you check that 354 + 307 = 661?

    Subtract one addend from the sum: 661 − 307 = 354, and 661 − 354 = 307. Getting the other addend back means the sum is right.

    How many carries are there in 354 + 307?

    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 307 + 354 the same as 354 + 307?

    Yes. Addition is commutative, so both give 661; the column looks the same with either number on top.
