[求助]这是什么意思啊看不懂

A teacher says: I'm thinking of two natural numbers bigger than 1. Try to guess what they are.
The first student knows their product(乘积) and the other one knows their sum.
First: I do not know the sum.
Second: I knew that. The sum is less than 14.
First: I knew that. However, now I know the numbers.
Second: And so do I.
What were the numbers?
