1=2 is a mathematically incorrect statemtent. I challenge anyone to prove otherwise.
For instance, you might say: a=b a^2=ab a^2b^2=abb^2 (a+b)(ab)=b(ab) a+b=b If a and b =1 1+1=1 2=1 This is a proof that I have seen all over this site. THIS PROOF IS INCORRECT!!! If a=b, then in the 4th line, when you divide by (ab), you are really dividing by 0, and that goes against the rules of math. I CHALLENGE SOMEONE TO PROVE ME WRONG. I CHALLENGE SOMEONE TO PROVE THAT 1=2.
Step 1; a and b > 0 Step 2: a = b Step 3: a2 = ab Step 4; a2  b2 = ab  b2 Step 5: (a + b)(a  b) = b(a  b) Step 6: (a + b) = b Step 7: b + b = b Step 8: 2b = b Step 9; 2 = 1 ha 1=2 

First off, I want to thank Idontcare for accepting this debate as his first one on this site *applause*. I shall now proceed and rip apart your proof *bows*
This is my opponent's proof: Step 1; a and b > 0 Step 2: a = b Step 3: a2 = ab Step 4; a2  b2 = ab  b2 Step 5: (a + b)(a  b) = b(a  b) Step 6: (a + b) = b Step 7: b + b = b Step 8: 2b = b Step 9; 2 = 1 ha 1=2 In step 5, by dividing by (ab), you are dividing by zero, something that is not allowed in math. If a=b, then if you subtract one from the other, you get zero. It is a well known mathematical fact that you CANNOT, I repeat, CANNOT divide by zero. Dividing by zero will only give you an undefined answer. For instance, let us say that a=5. Therefore, according to step 2, b=5. Right? If we plug a=b=5 into step 5, we get the following: (5+5)(55)=5(55) If we divide by (55), like my opponent did, we get the following: [(5+5)(0)]/0=[5(0]/0 THIS IS WRONG. YOU CANNOT DIVIDE BY ZERO. THANK YOU
with all honesty i knew that...... so do the rest of us and i just wanted to get this debate off the table we all know 1 cant equal two (Rolls eyes)

Also, if your proof allows 2 to equal 1, you have done your proof wrong. We know this because math is a perfect system, and so it cannot be flawed.
On the other hand, I am assuming that 1 = 2 from the very beginning, which, is generally assumed not to be true.
1 = 2
1 1
________
0 = 1
.5 .5
________
(.5 = .5) ^ 2
________
.25 = .25
