It's tricky,could you find out what is wrong in this----

1=1

1²=1*1

1²-1²=1*1-1²

(1+1)(1-1)=1(1-1)

1+1=1

i.e.2=1

I dont think there is anything tricky here.U r cancelling zero which is not possible.(u r cancelling (1-1))

let  x=y

2x-x = 2y-y

2(x-y) = x-y

divide on both sides by x-y

hence 1 =2
