Cool Stuff

Magic maths:

Infinity + 1 = Infinity cause that's the highest number ever!

Subtract Infinity from both side and you get:

0 = 1

Therefore 1 = 2, 2 = 3, 3 = 4 and so on. Weird?

.999...= 1

Let .9999...= x

Multiply both sides by 10:

9.9999... = 10x

Subtract x from both sides:

9 = 9x

Divide both sides by 9:

1 = x = .9999...

Therefore, zero point nine repeating is one! There's no trick there, it's just the way it is!

• If the government has no knowledge of aliens, then why does Title 14, Section 1211 of the Code of Federal Regulations, implemented on July 16, 1969, make it illegal for U.S. citizens to have any contact with extraterrestrials or their vehicles?
• The cigarette lighter was invented before the match.
