Proof for 1=2
solution:

a=b
a^2=ab
(a^2)-(b^2)=ab-(b^2)
(a+b)(a-b)=b(a-b) => a=b .....(1)
a+b=b
from equation (1)
b+b=b
1+1=1
2=1!!!



Warning : Opps if a=b then (a+b) *0 = b *0 so 0/0

i also prove 2+2=5
here
we know that
0=0
-20 = -20 (the is no problem to know what that)

16-36 = 25-45 (we Can Write The no problem still)

(4^2)-2(4)(9/2)+{(9/2)}^2=(5^2)-2(5)(9/2)+{(9/2)}^2

(just open it with the formula of (a-b)^2 which is ballance both side)

(4-9/2)^2 = (5-9/2)^2

(close the third equestion as (a-b)^2)
taking squre root both side
4-9/2= 5-9/2

( after that -9/2 is cancell)

4=5
we can write that

2+2= 5


Have FUN
