Question

Proof that 5+5+5=550 ( I know this is impossible but my uncle is asking to me plz help)

Answer 1

Actually, mathematically it is impossible to prove this equation.

It is a brain teaser which can be easily proven if you understand the logic behind this question and that is

Add a straight line to the first or second "+" to make it a "4".

5 + 5 + 5 = 550

5 4 5 + 5 = 550 or 5 + 545 = 550

Hence Proved.

Answer 2

Just put a small inclined line on any addition sign (+), so now it will look something like this:

5 4 5+5=550 or 5+5 4 5=550

equation is solved.
