 Pro Resolved: One plus one equals twoDefinitions:One: The first and lowest whole numberTwo: The second whole number, coming after oneRound one will be for acceptance only!Report this Argument Con I accept. Report this Argument Pro I'll begin this round by defining one additional term:Whole number: a natural numberhttp://en.wikipedia.org...Now, I will demonstrate that one plus one equals two in a mathematical proof:Let S be the successor function. By standard definition, 1 = S(0)2 = S(1) a + S(b) = S(a + b) Therefore, a + 1 = a + S(0) = S(a) 1 + 1 = 1 + S(0) = S(1) = 2 QEDI urge everyone to vote pro!References:http://en.wikipedia.org... Report this Argument Con 1 + 1 doesn't always equal two. a = 1b = 1Set a = b; Then multiply each side by a:a^2 = ab; Then subtract b^2 from each side:a^2 - b^2 = ab - b^2; Now factor each side:(a+b)(a-b) = b(a-b); Now divide each side by (a-b):a+b = b;In other words:1 + 1 = 1Report this Argument Pro In the final step of my opponent's "proof", she divides both sides of the equation by (a-b). However, a-b = 0, and division by zero is impossible (1). Therefore, 1 + 1 ≠ 1References:(1) http://en.wikipedia.org...Report this Argument Con If you combine the symbol 1 with the symbol 1, you have 11.1 + 1 = 11 Vote con! Report this Argument

The font I used DID appear normal on my computer screen:

Divide by (a-b)... lol...

a and b are different values, however 1 and 1 are similar values. Cons reasoning isn't legitimate.

Was there something wrong with the font I used? It appeared normal on my computer screen...

For those who found my argument to be confusing, I recommend reading this wikipedia article. The section on addition is particularly applicable.

For those who don't know, this is what Pro said (using word translator).

I'll begin this round by defining one additional term:

Whole number: a natural number
http://en.wikipedia.org......

Now, I will demonstrate that one plus one equals two in a mathematical proof:

Let S be the successor function. By standard definition,
1 = S(0)

2 = S(1)
a + S(b) = S(a + b)
Therefore,
a + 1 = a + S(0) = S(a)
1 + 1 = 1 + S(0) = S(1) = 2
QED

I urge everyone to vote pro!

Why would you use that font? I figured it out by pasting it into Word and changing the font but that just seems unnecessarily complicated.

Um what are you trying to prove in the second round?
