This video proves that 1+1=1
And you can certainly impress your math teacher with these tricks.
Although each method has a mistake but it's your task to identify the mistake. Actually its an #interesting #math problem.
When you show this amazing trick to your friends and teachers, they will be stunned, because it's generally difficult to identify which step is done wrong, although it's a simple #mathematics.

a-b=0 so it is impossible to cancel by (a-b)

You can't cancel a-b because it is 0. You can't divide by 0. DISPROVED

Bro I noticed a mistake! You can never cut zero or multiply zero on both sides of an equation. Or else, I will say one day for proving LHS=RHS, "Multiply 0 on both sides, 0=0" that is a rule of mathematics, that we cannot multiply or divide 0 in an equation. leave a comment if you are now aware of your mistake above.

If you let a=1, b=1 then the answer for your
Solution is zero. Let me proof it to you

(1+1)(1-1)=1(1-1)
2(0)=1(0)
0=0

You're wrong bro...

If you cut a piece of iron before hitting the tip of earth's atmosphere you would have 2 pieces of iron, 1+1=2. When entering space, watch the pieces mend back together. 1+1=1 for in space when you cut of piece of metal into 2 pieces it'll automatically recombine from the universal code which we haven't discovered yet

Here you cancel 0 by 0 it is biggest mistake

He is trying to divide by zero.... You cant

Okay so this is another example of a glaring mistake by manipulation.

First, you should never have different letters representing the same value.

Secondly, when it got to a² - b² = ab - b², the mistake was assuming that a² and ab are different but they are actually the same.

Therefore, (a + b) (a - b) = b (a - b) is an invalid operation. Either, the left side of the equal sign should be "b(a - b)" since a² = ab or the right side of the equal sign should be "(a + b) (a - b)" since ab = a². There are other variations that could be used, but I am limiting it to what was done in the video.

Therefore, you should get "b = b" or "a + b = a + b" depending on which way was chosen above.

Otherwise, you're just bad at math.

Recap:
a = b
a * a = a * b, multiply a to both sides
a² = ab, simplify like values. **REMEMBER THIS**
a² - b² = ab - b², subtract b² from both sides
(a + b) (a - b) = (a + b) (a - b), treat ab as if it is a² since they are equal
(a + b) = (a + b), divide both sides by (a - b)
Solution 1.) a = a, subtracted b from both sides
Solution 2.) b = b, subtracted a from both sides
Solution 3.) a = b, since a = b subtracted b from the left and subtracted a from the right
Solution 4.) b = a, since a = b subtracted a from the left and subtracted b from the right

Solutions 1 through 4 are all correct.

What the worst English are u speaking?

Basically at this line
(a+b)(a-b) = b(a-b)
When you divided both side by a-b
It leaves you with both side being undefined
Why? Let say (a+b)(a-b) = (1+1)(1-1) = 2×0 = 0
And you divided it by a-b = 1-1 = 0
Which is 0÷0
What is 0÷0? Its undefined

Another side which is b(a-b) same thing here
1(1-1) = 1-1 = 0
And you divided it by 0
0÷0 is also undefined
This leaves you with undefined = undefined

Man this guy is worst at math that me finally I am still better than some one

you cannot cancel a-b without checking the condition a-b=0 but respect

0/0=0. SO U CANT ERASE 0. (a+b)(a-b)=b(a-b) so when u devide with a-b, (a+b)(a-b)/(a-b)=b(a-b)/(a-b) . a=b=1.so a-b=0. -> (a+b)*0/0=b*0/0 ->(a+b)*0=b*0 haha gotcha
whtevr its funny math proof xD

a=1, b=1 <=> (a-b)=0 => (a-b)/(a-b)= wrong
