The following is my attempt at proving that 1<-1 . In which of these steps did I first make a mistake?

Step 1: Let i = sqrt(-1) then i^2 = -1 and i^4=1.

Step 2: Hence, we have i^2 < i^4

Step 3: We divide both sides by i to get i < i^3.

Step 4: We divide both sides by i again to get 1<i^2 or 1 < -1
