WALT: Add and subtract decimals.
This week we were given this think-board. The whole think-board is based around subtracting decimals. What I learnt is that when using partitioning for subtracting decimals, never spilt up the first number. I learnt never spilt up the first number but spilt up the second. For example: 2.534 - 1.112=?
2.534 - 1= 1.543
1.543 - 0.1=1.443
1.443 - 0.01=1.433
1.433 - 0.002=1.431
So the answer would be 1.431. Please comment to see what I did with the subtracting and partition.
