Is there any possible way of making 2+2=5?

*listens to the facepalm of many many dead famous mathematicians *

@sarah and @vrinda : Very Interesting. And this is where iota concept is useful. See,
2+2=4
4-9/2+9/2=4
Therefore Manipulating LHS:
(4-9/2)^2^1/2
Therefore,
(a^2+b^2-2ab)^1/2
((16-36+(9/2)^2)^1/2)-9/2
=((-20+(9/2)^2)^1/2)-9/2
=((25-45+(9/2)^2)^1/2)-9/2
=(5^2 - 2.5.9/2 +9/2^2) ^1/2 -9/2

=(5-9/2)^2 ^1/2 -9/2
=5-9/2+9/2
=5
Eq With RHS=4
5=4=2+2

@sarah Let 2 = 2.5, then 2+2 = 5

You're a genius, you should scam people!

2+2=4
4-9/2+9/2=4
Therefore Manipulating LHS:
(4-9/2)^2^1/2
Therefore,
(a^2+b^2+2ab)^1/2

Assuming a = 4 and b = 9/2, (a-b)^2 = (a^2 + b^2 - 2ab) = (16 - 36 + (9/2)^2)

((16-36-(9/2))^1/2)-9/2

Ahah, the sign in front of the (9/2) should be positive (and it's missing a square which you correct in the follow line)

=((-20-(9/2)^2)^1/2)-9/2
=((25-45-(9/2)^2)^1/2)-9/2
=(5^2 - 2.5.9/2 -9/2^2) ^1/2 -9/2

Assuming you meant =(5^2 - (2x5x9)/2 "-" (9/2)^2), the factorization should yield =(5^2 -(2x5)(9/2) "-" (9/2)^2), which is not (5-9/2)^2 = (5^2 -(2x5)(9/2) + (9/2)^2); the sign on the (9/2)^2 being the issue

=(5-9/2)^2 ^1/2 -9/2
=5-9/2+9/2
=5
Eq With RHS=4
5=4=2+2

Rest is history :)

@i-am-male It wont get you to 4=5, But the other way does. Well who knows, maybe 4=5 and this whole world is going crazy after all Neglecting Mathematics. I love it to solve these problems. On a serious note though if you do plot a Graph, I dont know how we could get 4=5 with this equation. We could plot it for: y=(a-b)^2. See where a=5 and b=9/2. Without considering iota, just hand plot it. Results would be amazing.

[BloodDrunk]

No, there isn't, because if you do indeed manage to find a way, then you made a mistake somewhere.

[khaleex]

my head hurt from reading the converstion between the guys (im pretty sure those two are) below. yes there is a way for 2+2 to become 5... just add freaking 1. you said "making" not proving that 2+2 is 5.

[Piyush Kumar]

based,on pure math i dont think it is possible

[zeddy]

Well if one of the couple isnt wearing protection, then 💁🏻‍♂️😂

[Maverick832]

@i-am-male You were Right. I dont like it to do on Computer, this Maths. So I corrected it and it was just one only. The sign before 9/2 should be positive before squaring. So that is it, and it still yeilds, 4=5=2+2

[Maverick832]

@maverick832 And The rest is History NOW. And I dont SCAM people in MATHS Atleast, but I love doing it in real life. ;)
And Identify the problem now. Still there is one. But mathematically saying the solution is purely correct now.

[Ephemeral]

@maverick832 You mean the -9/2 on the outside that was supposed to be +9/2?

Or do you mean the part where I reveal the secret to this trick where you basically kill the negative sign that comes from (4-9/2) = -0.5 by squaring the (4-9/2)^2^(1/2) = +0.5 without accounting for complex numbers (i)

[Maverick832]

@I-Am-Male See the solution. Corrected it.

[Maverick832]

@i-am-male And The Hint is Squaring a negation is never a problem, rooting it is. I will tell you a problem with my method, umm well its not mine though, my teacher got it to us in 8th Standard. The problem is, I considered only one root :) Buddy.

[Ephemeral]

@maverick832 Yeah you corrected it at the last step, that's why I didn't point it out previously.

[Maverick832]

@i-am-male So got the problem?? But you agree right that mathematically its correct ;)

[Ephemeral]

@maverick832 Lol you just said the problem here is you didn't account for the second root, I was referring to complex numbers as a way to track the negative root.

I would like to quote here that there are some things in world even Mathematics feels powerless. I keep it to God.

[Maverick832]

@maverick832 Same way we obtained pi. Through Integration. But we did not account for many values, and that is why pi is irrational though 22/7 is purely rational
