3 + 2 = 4 Proved | How to prove it.

3 + 2 = 4 Proved | How to prove it?
3+2 = 4 can be proved by breaking the ground rules of mathematics. According to mathematics, it is well known to everybody that 3 + 2 = 5. But I have proved through funny math tricks that everything is possible through mathematics if you can break the rules of mathematics. However, as like as other math riddles, this 3 + 2= 4 funny proof is also able to spin anyone's head. The step by step solutions of this 2+3=4 riddles is described here in this amazing math facts video. It is also given the best math proof about how to prove 3+2 = 4. The facts about mathematics are that if someone skips or do a single mistake, the final result would bring a strange output. The same scenario happens in this 2+3=4 fun of mathematics video.
If someone interested to catch that 3 + 2 = 4 kaise hota hai, write it in the comments section and let's discuss there.

A easier way :
4–4 = 10–10
=> 2²–2² = 5(2–2 )
=> (2+2)(2–2) = 5(2–2)
=> (2+2) = 5
=> 2+2 = 2+3
=> 4 = 2+3
=> 2+3 = 4
Hence, proved.
This type of sums are just for fun.
Mathematics doesn't allow such sums.
So don't consider them.
It is just fun to know about them.
Never use them is daily life.
These sums are not possible because numbers like (2-2), as I have written, is equal to 0. Hence it finally means multiplying by 0, so the final answers are always 0. Moreover dividing a number by 0 means "not defined".
A mathematics teacher will never teach such sums.
Thanking you,

She: but i am just 13
Maths dudes: Lemme show you how you are actually 18

Line 6) Step of Taking under root on both sides is wrong because on left the whole number is negative while on left side the whole number is if you are taking under root you have to put a negative sign infront of the (4-9/2) and hence the equation will become
1)Left hand side is negative
2)you take the under root but forgot to put a negative sign because squaring of 2 also gives 4 and squaring of -2 also gives 4 but -2!=

Who is just seeing for confusing their mates😆

[amarnathsingh]

7:09 here, After taking root on both sides we use (+ -), So 5 - 9/2 = 4 - 9/2 or 5 - 9/2 = 9/2 - 4 which has two solutions. either 4 = 5 (not possible) or 5+4 = 9 (Correct). If you love maths please don't ruin it.

[aryamaanjadeja]

The only difference between you and me is that you have a explanation and I don’t.

🤣🤣

[mouryamandapati]

While you want to square root of negative integers like -x there is possibility that i^2=-1
Means value of "i" is always uncertain so you cannot apply square root on LHS and RHS without involving complex numbers.

More simple trick but solving in short cut
We can say,
20 - 20 = 25 - 25
So, (4*5)-(4*5) = (5*5)-(5*5)
Taking common on both sides,
4(5-5) = 5(5-5). {Can verify by multiplying}
Cut (5-5) on both sides as in multiplication form. Without solving the brackets.
So, 4 = 5
We can say 4 = 3 + 2 or 3+2 = 4.
(Simple method, no use of formulas)
I want more likes to comment than the video.😂

MY ANSWER:

If 5 = 4, then
4 = 5
On the left hand side, it becomes,
(2)^2 = 5
√[(2)^2] = √(5)
Note that the symbol "√" is the "square root". That is,
2 = √5
Divide both sides by 2, and therefore

1 = (√5)/2 ✌️😜😅

[sora_]

adding 81 over 9 was already the mistake, that is an equation based on the fact that the main components were -20

[sergiydobrovolskyy]

7:28 here.
A squared term (4-(9/2))^2 being equivalent to (5-(9/2))^2 is an insufficient condition for asserting that both terms without the power are equivalent.
Let (4-(9/2))^2 = a^2 (=) a^2 = b (=) a = +/- √b or +/- 0.5 (binary solution set, with two signs possible: + and -)
Let (5-(9/2))^2 = a^2 (=) a^2 = b (=) a = +/- √b or +/- 0.5 (binary solution set, with two signs possible: + and -)
So, cutting the even square for the two terms in the equation is wrong since:
1) While odd-index roots admit only one solution, even-index roots admit a binary solution-set with two possible solutions.
2) Equivaluating only one of the possible solutions (-a) of a solution-set to another solution (a) of another solution-set is prone to errors, because there are three possible combinations for the equations with two terms of even-index roots, a = a, a = -a and -a = -a, or as in this case, 0.5 = 0.5, 0.5 = -0.5 and -0.5 = -0.5, of which one is wrong as 0.5 = -0.5.

[MateuszStrompowski]

Mistake is that 4-9/2 is negative, so you must change it to positive and you have 0.5=0.5. You can't just cancel the power of 2 by using root, you convert it to the absolute value.

[dragongaming]

ACTUALLY, WE HAVE TWO ANSWERS OF A SQUARE ROOT OF +1.... √1 = -1 Or +1.. .

AND THAT IS THE TRICKY PART OF THIS MATHEMATICAL ILLUSION... IF WE FOLLOW THOSE THINGS PROPERLY... THEN ILLUSION ISN'T HAPPEN...

AND ALSO WE KNOW I=√-1... So i² = 1 ... From there we also get much more things whatever u need...

THANK YOU ❤❤❤...

[nabinlama]

After line 5 you should use the rule of BODMAS, meaning there is square of a whole bracket....so that is to be solved if solvable before square rooting or cutting the squares off

[emad]

people remember, when you take the even root of a number there are actually TWO results (positive and negative) and at least one is true
so if we assumed that square root of (4-9/2)^2 = -(4-9/2) = 9/2-4
the result will be 9=9 which is true

[ajoykumarmahato]

The mistake is simple :-
At starting you had :-
( - 20 = - 20 )
And, at ending you are having :-
4 - ( 9 ÷ 2 ) = 5 - ( 9 ÷ 2 )
- 0.5 = 0.5

[film-gqwg]

the mistake here is line 6
here's 2 ways of correcting it
1)
(4-9/2)² = (5-9/2)²
0 = (5-9/2)² - (4-9/2)²
use a²-b² = (a+b)(a-b)
0 = (5-9/2+4-9/2)(5-9/2-4+9/2)
= (9-18/2)(1)
= (9-9)
= 0
which is true
2)
(4-9/2)² = (5-9/2)²
we take the sqrt of both side
√[(4-9/2)²] = √[(5-9/2)²]
we know that √(a²) = |a|
so
|4-9/2| = |5-9/2|
we use the pattern
|f(x)| = |g(x)| -> f(x) = g(x) or f(x) = -g(x)
4-9/2 = 5-9/2
4 = 5 which is false
or
4-9/2 = -5+9/2
9 = 18/2
9 = 9
which is true
that's make the equation holds true

which mean the mistake comes from line 6
