Remember NO GOOLGING or SEARCHING the Internet allowed and good luck!!!!!!!!!!!!!!

RIDDLE: n + n + .... n times = n^2.

differentiating both sides with n we get

1 + 1 +.... n times = 2*n

or

n = 2*n


find the flaw?

    n=0
    n=0 is the only thing I could come up with.

    0^2=0

    1*0=0

    0=2*0
