nIndecided to talk about big numbers because of the following historicalnanniversaries:

nAlson on this date in 1998, AT&T bought cable TV companyn Tele-Communications, Inc., for $31.7 billion.

nInwrote them in this order to go from smallest to largest of the bignnumbers. But the big numbers are written in different formats – sonit is harder to see how they relate to one another.
n
n
n
n
n
nHerenthe numbers are written ONLY with numerals, no words:

nYikes,nthose numbers are big!
n
n
n
n
n
nButnthey aren’t as big as the numbers that scientists use! Thosenthousands, millions, and billions are swamped by the trillions andnsextillions and decillions and much, much greater numbers!
n
n
n
n
n
n
n
nThat’s partly because the universe is really, really, really, really huge! And because the universe is made up of things that are really, really, really tiny.
n
n
n
n
n
nIt’s also partly because networks – like the network made by all of the interconnected neurons in our brain, and like the internet (pictured here, right) – end up with large numbers of connections and nodes.
n
n
n
n
n
n
n
n
n
n
n
nHerenare some examples of how we might use those numbers:
