FAQ

What is 203 + 98?

203 + 98 = 301

How do you check that 203 + 98 = 301?

Subtract one addend from the sum: 301 − 98 = 203, and 301 − 203 = 98. Getting the other addend back means the sum is right.

How many carries are there in 203 + 98?

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 98 + 203 the same as 203 + 98?

Yes. Addition is commutative, so both give 301; the column looks the same with either number on top.
