FAQ

What is 888 + 12?

888 + 12 = 900

How do you check that 888 + 12 = 900?

Subtract one addend from the sum: 900 − 12 = 888, and 900 − 888 = 12. Getting the other addend back means the sum is right.

How many carries are there in 888 + 12?

2 carries: 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 12 + 888 the same as 888 + 12?

Yes. Addition is commutative, so both give 900; the column looks the same with either number on top.
