Great review on mathematical induction

those are all damn assumptions, man there is no really true proof out there, it makes people feel fake

You just simply plug in the numbers to stupidly test whether the equation is right or wrong, no one should believe this bull, here is the right way of proving: let's assume a number: sum = then 10*sum = then 9*sum =10^(n+1) -1, then sum = 10/9(10^n - 1).
