Part 1: Elementary Calculations

Each of the command entry instructions below is sent to Maple for processing by pressing the RETURN or ENTER key on your keyboard.

1. In the Maple worksheet, type
   2 + 3
   and then press RETURN or ENTER. (From now on, we will not add this last part of the instruction.)
2. Enter
   2 - 3
   
   
3. Enter
   2*3

Note that Maple automatically changes the asterisk to a dot, so that the formula is in standard mathematical notation.

4. Enter 
   6/3

   Note that Maple automatically knows that you are going to type in a fraction and changes it to:
   
   6
   -
   3
   

5. Enter
   2^3
   
   Note that Maple automatically knows that you are going to type in a exponent and changes it to:
   
   2³
6. Enter
   2*(8 - 2^3)
   
   
7. Enter
   2^3 + 1
   
   Is the answer what you expected?  In order to get the correct answer (which is 9) you need to press the right arrow key after the number 3.  This moves the cursor out of the exponent so that you get 
   
   2³ + 1
   
   
   as desired.
