How do you check that 1,917 + 83 = 2,000?

Subtract one addend from the sum: 2,000 − 83 = 1,917, and 2,000 − 1,917 = 83. Getting the other addend back means the sum is right.

How many carries are there in 1,917 + 83?

3 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 + 1,917 the same as 1,917 + 83?

Yes. Addition is commutative, so both give 2,000; the column looks the same with either number on top.
