How many carries are there in 71 + 34?

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 34 + 71 the same as 71 + 34?

Yes. Addition is commutative, so both give 105; the column looks the same with either number on top.
