find all two digit numbers where are the tens digit is 2 more than the ones
digit and each number is greater than 60
------
each number is greater than 60.
So the tens digit is either 6,7,8, or 9.
the tens digit is 2 more than the ones digit.
Rewrite that equivalently as
the ones digit is 2 less than the tens digit.
Thinking of it that way makes it easy:
2 less than 6,7,8,9 is 4,5,6,7 respectively.
