1. we thought of a equation then we split the second number up in hundreds ten and ones. Then we subtracted the 498 with the 300 which we got 198. Then we subtracted the 198 with 60 which we got 138. Then we subtracted 138 with 7 which we got 131. So the answer was 131!

Reflection : it was easy because we have done this a lot. I can now use a poppet and I can do a subtraction on the popplet
