There is a lot of confusion over what googol and googolplex mean, and exactly how big they are.

Don't spread misinformation about these numbers! Learn the truth. And that's what I'll show you.

Googol was first coined by 9-year-old Milton Sirotta somewhere in the 1940's.

It is  (ten to the power of one hundred), or

100000000000000000000000000000000000000000000000000 00000000000000000000000000000000000000000000000000.

That's a one, followed by 100 zeroes.

How big is a googol?

A googol is much bigger than a million. Million is only 1000000 =.

A googol is much bigger than a billion. Billion is only 1000000000 =.

A googol is much bigger than a trillion.

A googol is much bigger than a quadrillion.

...

Googol, however, is smaller than trestrigintillion, which is the 33rd number in this sequence.
