Question

20 = (20)^2 - (20)^2/ 20-20 = (20-20)× (20+20)/ 20-20=20+20=40 but how is it possible

Answer 1

$20 = \frac{ {20}^{2} - {20}^{2} }{20 - 20} \: \\ 20 = \frac{(20 + 20)(20 - 20)}{(20 - 20)} \\ 20 = 20 + 20 \\ 20 = 40$

This was possible because we have taken infinite equals 20 . We have taken 0/0 as a finite value. But it equals a infinite value.
