Number problems is one of the most common problems in many math competitions including MTAP Grade 5 and MTAP Grade 6. We discuss some work examples on number problems in this post. Little algebra is needed to solve this type of problem, but it is expected from advanced students who join math competitions.

**Number Problem**

One number is 2 more than the other. Their sum is 28. What are the numbers?
