Question 642637
It Is Less Than 70 And Greater Than 65. If You Add The Two Digits , 
The Sum Is 14
------
I would list the integers that are greater than 65 and less than 70.
66::::67::::68::::69
------
Then I would talk to him about adding 
6+6, 6+7,6+8,6+9.
----
Hopefully we would see that 6+8 = 14
