FAQ

What is 203 + 74?

203 + 74 = 277

How do you check that 203 + 74 = 277?

Subtract one addend from the sum: 277 − 74 = 203, and 277 − 203 = 74. Getting the other addend back means the sum is right.

How many carries are there in 203 + 74?

None: no column adds up to 10 or more, so every digit of the sum is written straight away.

Is 74 + 203 the same as 203 + 74?

Yes. Addition is commutative, so both give 277; the column looks the same with either number on top.
