# Video tutorial: Infinite series

In this short video, I explore the math behind this joke: An infinite number of mathematicians walk into a bar.
  The 1st orders a 1     beer.
The 2nd orders   1/2 a beer.
The 3rd orders   1/4 a beer.
...
The bartender says
"You're all idiots",
and pours two beers.
We will make sure MATLAB shows values as fractions and not decimals and plot the cumulative some of this series
