Please could you give me some idea what age and level these sums would be suitable for (written (ie not mental maths)to be solved by partitioning
62+12
15+12
36+11
56+23
64+21
42+34
21+25
45+32
I know it may not be possible to say exactly and it depends on circumstances etc, but just taking it at face value, a rough idea.3
Many thanks in advance
