Hi everyone, I have to make a proof by induction :
"n ∈ Z, Show tat 3|n^2 => 3|n"
Thank you for your help :)
 
Do two things:

1) Write down the verbal meaning of that symbol, "|". Make sure you know which way it goes. Does the first divide the second or the other way round?
2) Write down an algebraic expression that means what you described in Part 1.
