Our explanation
All the numbers we have used like : 63
63-9=54(frog)
6+3=9
or
27-9=18(frog)
2+7=9
If you look at the numbers 63,54,27 and 18 they all have something in common:they are all in the 9 times tables.
Also you can see that 6+3 and 2+7=9 so you have to subtract by 9 to get a nine times table answer!
