FAQ

What is 203 + 19?

203 + 19 = 222

How do you check that 203 + 19 = 222?

Subtract one addend from the sum: 222 − 19 = 203, and 222 − 203 = 19. Getting the other addend back means the sum is right.

How many carries are there in 203 + 19?

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 19 + 203 the same as 203 + 19?

Yes. Addition is commutative, so both give 222; the column looks the same with either number on top.
