Homework Statement
The thing is that there is a question which needs me to prove something. I have done it already but the thing that troubles me is that it wants me to prove this:
[tex]a_{1}+a_{2}+a_{3}+....a_{K}>K[/tex]
[tex]a_{i}[/tex] is a positive integer.
I know this is always true. but how should I prove it mathematically?
