The road to understanding is rough; 

Run, Run! 2 = 1!  
Theorem:  2 = 1 
Proof:  
Given:  A = B 
Multiply by A:  A^{2 }= BA 
Subtract B^{2}:  A^{2 }– B^{2} = BA – B^{2} 
Factor:  (A + B) (A – B) = B (A – B) 
Cancel:  (A + B) = B 
Substitute:  B + B = B 
Collect:  2B = B 
Cancel:  2 = 1 
QED!  
Logic will get you from A to B. 

Run, Run! 2 = 1!
