Use mathematical induction to prove, for all integers [itex]n >= 1[/itex]

[itex]n^3 - n[/itex] is divisible by 3

2. Relevant equations

Found equations with addition but no subtract involved.

3. The attempt at a solution

Another question suggests you expand the brackets, then insert the original theorem which prooves that the whole statement is true? (divisible by 3)
