Part 1: Elementary Calculations
Each of the command entry instructions below is sent to Mathematica for processing by pressing SHIFTRETURN (hold down the SHIFT key and press the RETURN key on your keyboard).
Note: Your first calculation will take longer than subsequent calculations because the Mathematica kernel has to start up. (Mathematica is made of two parts: a kernel and a front end. The kernel is the part that does calculations. The front end is the part that handles notebooks and interaction with the user.)
