 Today is the first day of Mathematical computing with Mathematica. We will use
which is available on all campus computers. This is an old, but still powerful, version of this software.

 Power off your computer

There are five types of brackets in Mathematica:
 ( )  parentheses or round brackets  for grouping terms  ((E^(I Pi)) + 1)
 [ ]  square brackets or box brackets  for arguments of functions  Cos[Pi/5]
 { }  braces or curly brackets  use them to put things together in a list  {1, 0, Pi, E, I}
 [[ ]]  double square brackets  use them with lists  {1, 0, Pi, E, I}[[4]]
 (* *)  starred parentheses  for comments in Mathematica code  (* this is ignored *)

Pay attention to the structure and design of the cells in a notebook. If you want to put text in an Input cell, then it must be enclosed in (* *)
