FAQ

What is 517 + 83?

517 + 83 = 600

How do you check that 517 + 83 = 600?

Subtract one addend from the sum: 600 − 83 = 517, and 600 − 517 = 83. Getting the other addend back means the sum is right.

How many carries are there in 517 + 83?

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 83 + 517 the same as 517 + 83?

Yes. Addition is commutative, so both give 600; the column looks the same with either number on top.
