FAQ

What is 376 + 15?

376 + 15 = 391

How do you check that 376 + 15 = 391?

Subtract one addend from the sum: 391 − 15 = 376, and 391 − 376 = 15. Getting the other addend back means the sum is right.

How many carries are there in 376 + 15?

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 15 + 376 the same as 376 + 15?

Yes. Addition is commutative, so both give 391; the column looks the same with either number on top.
