Now Lets check another Mathematical Illusion: To prove 1=2 Let, x=y or, 2x-x=2y-y or, 2x-2y=x-y or, 2(x-y)=x-y or, 2=1 |

In last step u have divided by (x-y) to both side. As 1st x = y, therefore x-y=0. but as per 1 of the basic rule of mathematics u can not divide by zero("0"0 to any thing. Dividing by zero has no meaning.
therefore above conclusion is incorrect.
also for 100paisa=1 * 100paisa but not 1paisa * 100paisa cuz,
if i have Rs.10,000 ( all are Rs. 100 currency note) then i write it as,
100 * Rs. 100. I am not writting it as Rs.100 * Rs.100.
So there is no such word called as illusion in mathematics. :D
