List all pairs of 1 digit numbers that add up to 13. Put the odd digit as the units digit, and the even, tens.
I start off with:
4,9
8,5
...
The sum of my two digits is 13. I am not divisible by 2. List all possible numbers I could be.

How does this satisfy the "not divisible by two" rule? I think the answer is 1 and 3 and sum does not mean addition in this case it means to combine 1 and 3 to make 13...what do you think?
Not divisible by two means that the resulting number is odd, like 49 (and not 94).
Sum is the result of addition.
Sum of "my two digits" means 4+9 if the number is 49.
Give it another try.
