Theorem: 3=4
Proof:

Suppose:
a + b = c

This can also be written as:
4a - 3a + 4b - 3b = 4c - 3c

After reorganizing:
4a + 4b - 4c = 3a + 3b - 3c

Take the constants out of the brackets:
4 * (a+b-c) = 3 * (a+b-c)

Remove the same term left and right:
4 = 3

Much easier

3 x 0 = 0
4 x 0 = 0

3 x 0 = 4 x 0

Divide each side by 0

3 = 4

devil, you cannot divide zero with zero. Or you cannot even divide any numbers with zero just fyi.

DUH !!!! I wonder why no one ever told me that before, when I was doing degree maths????

[garbitsch]

Now you've learnt it

[nasos007]

reminds me of the Salary Theorem (the less you know, the more you make).
Proof:

Postulate 1: Knowledge is Power.
Postulate 2: Time is Money.
As every engineer knows: Power = Work / Time
And since Knowledge = Power and Time = Money
It is therefore true that Knowledge = Work / Money .
Solving for Money, we get:
Money = Work / Knowledge
Thus, as Knowledge approaches zero, Money approaches infinity, regardless of the amount of Work done.

Isn't that what Sotos did by dividing by (a+b-c), also zero,
or am I missing something?

[dms007]

for that matter its not just 3=4, any two consequtive natural numbers can be "proved" to be equal

[dms007]

but.... to the finer eye

4 * (a+b-c) = 3 * (a+b-c)

is where the flaw is......

a+b=c
so a+b-c=0

so effectively it becomes

4*0=3*0

since in the original post the expression is being divided by (a+b-c) which is actually 0 the division will fail, 0 divided by zero is undefined.

so all that we can prove is 0=0 which is true for all numbers.

Which is why my version, which Garbitsch tried to trash, is much easier: it is exactly the same.
