Some super genius at my school taught me this little trick to prove 4 = 5. He'll be attending college after his junior year at Greenhill School! But honestly, I don't see why someone would do that. Senior year is supposed to be the best!
a + b = c
Form two separate equations, and multiply one by 4, and the other by 5.
4a + 4b = 4c .............. 5a + 5b = 5c
Subtract 4c from both sides on the first equation, and subtract 5c from both sides on the second equation.
4a + 4b 4c = 0 ................. 5a + 5b 5c = 0
Because both now equal 0, they must equal the same.
4a + 4b 4c = 5a + 5b 5c
Factor out the 4 on one side, and the 5 on the other.
4(a + b c) = 5(a + b c)
Now divide each side by a + b c
4 = 5
Cool eh?
Can someone spot the mistake?
EDIT: spacing not correct
