Con

2 Rounds. First is acceptance.

I do not think 2+2=4
ishallannoyyo

Pro

Someone has creating an Ishall2 (Airmax can do an IP check, it isn't me). I am severly insulted. Let us begin this debate on whether or not 2 + 2 = 4.
Debate Round No. 1

Con

Let a & b each be equal to 1. Since a ^ b are equal,

b^2 = ab ...(eq.1)

Since a equals itself, it is obvious that

a^2 = a^2 ...(eq.2)

Subtract equation 1 from equation 2. This yeilds

(a^2) - (b^2) = (a^2)-ab ...(eq. 3)

We can factor both sides of the equation; (a^2)-ab equals a(a-b). Likewise, (a^2)-(b^2) equals (a + b)(a - b) (Nothing fishy is going on here. Ths statement is perfectly true. Plug in numbers and see for yourself!) Substituting into the equation 3 , we get

(a+b)(a-b) = a (a-b) ...(eq.5)

So far, so good. Now divide both sides of the equation by (a-b) and we get

a + b = a ...(eq.5)

b = 0 ...(eq.6)

But we set b to 1 at the very beginning of this proof, so this means that

1 = 0 ...(eq.7)

...Anyways, getting that far gives us the jist of the proof, later in the proof, Charles Seife goes on to prove that Winston Churchill was a carrot! if you want to know how that is possible, I recommend you read the book.
From equation 7, add a number to either side and get it equal to any other number, one greater than itself.
Multiplying equation 7 after adding to it, and one can get: any number is equal to any other number. Therefore 2+2 is 5.

Pro

This is all under the assumption that "a" and "b" are equal, which they clearly cannot be as they are different variables.

x cannot equal y, they are different variables. Each variable denotes a specific number. Why then would there be "a" and "b"? Why not just "a" as there is no difference between "a" and "b"? This is like saying 4 = 5, clearly incorrect.

Easy vote CON (as this is a troll debate and my opponent's math was severely flawed)

2 variables can equal the same thing in the same equation. for example, on a graph we can have a point (5,5). x=5 and y=5. Simple.

also the first step is not mathematically correct. b^2=ab and a^2=a^2. You cannot subtract each side of an equation by two different numbers it should say (b^2)-(a^2)=ab-(a^2). It seems like a small change but you turn both the (a^2) into -(a^2) and the -(b^2) into (b^2) and the -ab into ab. The reason is that you should subtract both sides by the same number (a^2) instead of subtracting one side by (b^2) and ab.

: (a+b)(a-b) = a (a-b)
: So far, so good. Now divide both sides of the equation by (a-b) and we get
: a + b = a

You can't divide by zero, (a-b)=(1-1)=0 . This step is illegal. It's like when people say 2/0=0, therefore, 0*0=6. Sorry if this ruined the debate for you AznWords.

To Pro: a can equal b unless otherwise stated. Also: a & b in this context are given as constants not variables.

2 variables can equal each other in the same equation...if a = 1 and b = 1 then a = b.

Yes, but not in a single equation.

You don't understand variables! 2 VARIABLES CAN EQUAL THE SAME THING.

Reasons for voting decision: Despite the fact that CON's math was flawed, PRO never showed how CON's math was flawed. All he did was say that a =/= b without providing any reason for that justification. All PRO does is ask questions which are never answered and do not take the place of variables. Therefore, ever so reluctantly, I must vote CON since their arguments stood until the end. And PRO never provided any reasoning behind their arguments....:/ And to counter-act the VBs....

Reasons for voting decision: Con's argument made no sense, although Pro blatantly divided by zero. Arguments to no one, because neither of them was convincing.

Reasons for voting decision: Con brought up such a give away debate but Pro simply threw it away. Cons mathematical fallacy is quite an easy fix. Since this is an essentially 1 round argument I have to evaluate based on the last round. Even though Con is wrong, he is not overtly wrong while pro appears not to understand math very well. What Pro has stated is a blatant misunderstanding of math. There is no mathematical convention that restricts two variables from equaling and pro has not given reason for this restriction.
