Proof 4=5

[aragon]

If you weak in Math and no hope to even pass, show the examiner you can prove 4 = 5.

Let
b = a = 4

thus,
b = a

Since ab = ab,
ab + b = ab + a

Transpose b,
ab = ab + a - b

Subtract b² from both sides
ab - b² = ab - b² + a - b

Factor
b(a - b) = b(a - b) + (a - b)

Factor
b(a - b) = (a - b)(b + 1)
Divide:
b = b + 1
Since b = 4,
4 = 4 + 1

.·.
4 = 5

this is reaaly simple dude....here (a-b)=0

 

[TharinduNadunPerera]

so when you divide o by o it is not 1

ya ya... I jst put this one, just to have a look.
dividing by zero z not define in mathz ..
