Because if X=1 and Y=1 then X=Y because X and Y are the same number... [/b][/quote] but we cant get equal to unknown symbols! i mean x=y

But 2 isn't 1. 1 is 1. It isn't the way I work it out. It's the final answer that matters. And you say its (1+1)=1. I find that to be a no solution. Because it's like saying 9=10, which is not true. Therefore, no solution. I never came accross a answer that had something like 2=1 and not put no solution as the true answer. Ya get me? [/b][/quote] oh yah thats i wat thought too. see they probably saw it as 1+1=1 whereas we saw it as (1+1)=1 and then you work the brackets to get 2=1.

That statement contradicts itself when it says: "X=Y .:. (therefore) (X+Y)=y It would make sense if (X+Y) is established to be X or Y .:. X=Y and Y=Y, and so yes, 1+1 would equal 1

I'm just sticking to what my teacher taught me. As far as I know 2 is not 1. Now two ones are two. But since there is only one 1 in the right side, than 1 isn't 2. 2 is 2. 3-2 is 1.

and another question, why are x and y of the same value? shouldn't they be different hence the x and y? or am i too stupid to understand this.........

Because, if X equals Y, then X plus Y has to equal Y. [/b][/quote] Okay, lets say x=y. X is 3 and y is 3 lets say. Now, X plus Y has to equal Y. X+Y=Y. Lets plug it in 3+3=3 6=3. Still don't get it. lol..

I'm not even an algebra geek and I can figure this out. All its doing is cancelling itself out until it returns back to one. 1x1 is enough. Its basically the algebraic formula of 1x1 which DOES indeed equal 1. Stop burning your brains over it, the reasoning behind this is right in front of your face. Yes its in a term an 'illegal' math equation, but because of the way in which it is done, it MUST equal 1 if X=1 and Y=1. It is technically not a correct problem and indeed a "No solution" problem, but if done in the way it is done (1+1)=1. Notice that it has parenthesis, that automatically tells you it is multiplied. Why? Because look at this (1+1)(1+1) Your mind automatically tells you those two problems should be multiplied together. Thus bringing me back to the point that this is only the algebraic formula for 1x1. And kids, what did we learn about multiplying a number by one? It always equals itself .

True. But take what I said to any math teacher and they will agree with me on this. It's not complicated, its more like common sense. The numbers are cancelling themselves out until they reach 1.

You cancel out the equation... NOT solve it You cancel down until you can't cancel down anymore... When you do this it leaves the answer: 1+1=1
