The main points for today:

• What to do if things go wrong? There are 5 ordered actions that you can do.
  
  1. Abort evaluation in Kernel menu, keyboard shortcut Alt+.
  2. Quit kernel in Kernel menu,
  3. Exit Mathematica in File menu Alt+F4
  4. Ctrl+Alt+Del
  5. 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 should be enclosed in (* *)

• 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.
