Google's named after "googol," an incredibly large number — misspelled. Does it surprise you that the search engine makes mistakes with math, too? Just for fun, watch what happens when you use the Google calculator to solve equations involving a Googol (10^100).

Click each formula to see Google's calculator results:

10^100

(10^100) - (10^6) = 1.0 × 10^100

(10^100) - (10^90) = 1.0 × 10^100

With a few minutes' patience, you can do any of the above calculations by hand on a white board. A hundred digits isn't really that many. But Google shouldn't feel too bad — my copy of Excel failed the test, too.
