5=4 !!!

14 =14

10+4 = 10+4

10-10=4-4

\(10-10=2^{2} -2^{2}\)

5(2-2)=(2-2)(2+2)

=> 5=2+2

=>5=4

where is the mistake ??

\(\frac {2-2} {2-2}\) is indeterminate, not 1... Roman Frago · 1 year, 11 months ago

Division by zero is not allowed. If so, then 999999999 = 1 because 999999999(0) = 1(0) Leomar Nogot · 1 year, 10 months ago

@Leomar Nogot well this was what exactly i said to my friend when he asked me but he didn't agree and said that " what if i didn't keep the value of 2 - 2 ." :p

@Ashwin Upadhyay It's a little big, but yeah i just checked it and i'll start solving your set's problems by this evening. Thanks, dude. Matheus Abrão Abdala · 1 year, 10 months ago

@Matheus Abrão Abdala Thanks for trying it.

ya i know that its long but i didn't broke it into more sets because i was tired to classify them as it is truly long.

but i think that it a nice set as most of the questions don't need higher maths and rules (which i don't know :p)

P.S sorry for replying late but i couldn't reply as my 10th class exams are going on. Ashwin Upadhyay · 1 year, 10 months ago

@Ashwin Upadhyay Don't worry, dude xD. I am solving your set really slowly because I just started college this monday, and I'm moving things, getting my driver's license and everything else, so i'm really busy too. I'll finish as soon as I can. Matheus Abrão Abdala · 1 year, 10 months ago
