FAQ

What is 136 + 12?

136 + 12 = 148

How do you check that 136 + 12 = 148?

Subtract one addend from the sum: 148 − 12 = 136, and 148 − 136 = 12. Getting the other addend back means the sum is right.

How many carries are there in 136 + 12?

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

Is 12 + 136 the same as 136 + 12?

Yes. Addition is commutative, so both give 148; the column looks the same with either number on top.
