Are there any actual real proofs that another number equals another number? For instance i have seen more than one person with the signature:
Since ∞ + 2 = ∞ and ∞ - 4 = ∞
Then ∞ + 2 = ∞ - 4
So 2 + 4 = 0
Then 2 = -4
this obviously isn' true because:
If ∞ = ∞ + 2 AND ∞ = ∞ - 4
then taking ∞ from both sides of
∞ + 2 = ∞ -4
would result in
0 = 0
as both sides equate to ∞.
Also there is the one we were taught in maths:
x = y.
Then x^2 = xy.
Subtract the same thing from both sides:
x^2 - y^2 = xy - y^2.
Dividing by (x-y), obtain
x + y = y.
Since x = y, we see that
2 y = y.
Thus 2 = 1, since we started with y nonzero.
Subtracting 1 from both sides,
1 = 0.
This one isn't real as halfway through you divide by (x-y) which, because at the beginning it was stated x=y, means you have divided by zero, which
you can't do.
Another one is one i just made up and proves that 1=0
if 3y + 6z = 0
the dividing by (3y + 6z) gives
i am sure there is something wrong with it somewhere because it is obviously impossible....i'm not sure what's wrong with it though.
Anyone got any others? Or anyone tell me what is wrong with that last one?
