Proving that 1 + 1 = 3Date: 11/18/95 at 23:50:57 From: Anonymous Subject: 1+1 = 3 ? Hi, How can I show that 1+1 = 3 ? There is a possibility if you use sin and cos, but I don`t know how.

You cannot use correct mathematics to prove an incorrect statement. However, there are a couple of cutesie "proofs" of stuff like this, and you can use them to "prove" anything you want. The most famous example is the "proof" that 1 = 0, and once you prove anything that isn't true, you can prove ANYTHING else. You could prove that the moon is made of green cheese. You could prove that 5 = 8. You could prove that I'm your father. And yes, you could also prove that 1+1 = 3. That's because the statement p => q is always true when p is false. So that's the deal. -Doctor Ken, The Geometry Forum From: Anonymous Date: 11/22/95 at 23:50:57 Subject: 1+1 = 3 ? Can you give me a possible solution, an example?

Then x - y + y = y x - y + y y --------- = --- x-y x-y y y 1 + --- = --- x-y x-y 1 = 0 Now we know that 1 = 1, so add the following three equations together: 1 = 0 1 = 1 1 = 1 On the right is 1+1, and on the left is 3 ones, and 3 ones make 3. -Doctor Ken, The Geometry Forum |
