FAQ

What is 239 + 28?

239 + 28 = 267

How do you check that 239 + 28 = 267?

Subtract one addend from the sum: 267 − 28 = 239, and 267 − 239 = 28. Getting the other addend back means the sum is right.

How many carries are there in 239 + 28?

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 28 + 239 the same as 239 + 28?

Yes. Addition is commutative, so both give 267; the column looks the same with either number on top.
