Question

I am a 2-digit number. My ones is 3 more than my tens and the sum of my digits is 11. What number am I ?
Ms. Sue
5 + 6 = 11
4 + 7 = 11
3 + 8 = 11
2 + 9 = 11

Which of those meets the other criteria?
joel
3+8=11
Ms. Sue
Nope. There's only supposed to be a difference of 3.

8 - 3 = 5

joel

Ms. Sue
