Question 6:

(a) In the tens column, although the 1 has been carried over from the units, it has not been added to the 5 and the 7 to make 13, not 12. The answer should be 1035.

(b) When the 8, 9, 7 and the carried over 1 are added together in the tens column, it gives 25, so a 2 should be carried over into the hundreds column, not a 1. The answer should be 1356.
