This is what a googol looks like:
10,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000
America's debt is about 14 trillion, which looks like this:
14,000,000,000,000
I could therefore pay off the debt about this many times:
700,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000
Even if I paid off the debt that many times, I would still have this much money:
20,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000
In scientific notation, that would be 2x10^97. With that much money, I could then buy every single home in the world. Assuming that there are 4 billion such homes and the average price was 1 million dollars, the cost would be as follows:
4,000,000,000,000,000
That is also known as 4 quadrillion. I could then buy all buildings that aren't homes in the world. For the sake of this post, there are 10 billion such buildings with an average cost of 10 million. The cost would therefore be 100 quadrillion. Adding that to 4 quadrillion would make it this much:
104,000,000,000,000,000
I could repeat the home and building buying process this many times:
190,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000
Even if I did that, I would still have this much money left over:
240,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000
In scientific notation, that would be 2.4x10^95.
That just shows you how much a googol is.
