Question 22: Fill in the missing digits  in the sum.

How I worked it out: Well I started of on the right hand side and it said 7 + 6 = 5, Well I knew that was wrong. It equalled 13. So I added 2 to make it 15. Ten I went to the left and the numbers said 1+3=4, so what I did was carry the 1 from the 15 which made it 5. Everyone in grade 6 knows that 5+4=9. So thats what I put.

My answer: 17+42+36= 95
