FAQ

What is 19 + 12?

19 + 12 = 31

How do you check that 19 + 12 = 31?

Subtract one addend from the sum: 31 − 12 = 19, and 31 − 19 = 12. Getting the other addend back means the sum is right.

How many carries are there in 19 + 12?

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 12 + 19 the same as 19 + 12?

Yes. Addition is commutative, so both give 31; the column looks the same with either number on top.
