I would just like to point out that both systems were invented in Europe, just like the confusing month/day/year now used in the U.S. versus the day/month/year system used by the Brits and most other people when writing calendrical dates. Now, back to the counting problem. Interestingly enough, both methodologies have a history in France where both systems were used at alternate periods in its history. Well, here's the logic behind the American system:

1,000=thousand

1,000,000=million (basically a thousand thousand)

1,000,**000,000**=**bi**llion (2 sets of zeros after a thousand)

1,000,**000,000,000**=**tri**llion (3 sets of zeros after a thousand)

1,000,**000,000,000,000**=**quadr**illion (4 sets " " " " thousand)

1,000,**000,000,000,000,000**=**quint**illion (5 sets " " " " thousand)

.

.

.

You get the logic by now. Some other interesting numbers:

10^100 (ten to the hundredth power/to the power of 100)= googol (essentially one followed by a hundred zeros)

10^10^100= 10googol =googolplex (one followed by a googol zeros).

Hope this helps you understand our system.
