How many carries are there in 83 + 45?

1 carry: 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 45 + 83 the same as 83 + 45?

Yes. Addition is commutative, so both give 128; the column looks the same with either number on top.
