Exercises

Supply the commands to perform the following tasks

Assign 2 to the variable z
Use % to display z + 2
Use % to display z + 12
Use % to display z + 24
Use % to display z + 14
Use % to assign z*(z+14) to x
```
          z := 2
          % + 2
          % + 10
          % + 12
          % - 10
          x := z * %
        
```
Comment: Notice the sloppiness of using % for these tasks; it would be a lot easier to simply type z+2, z+12, etc.
Bring up the help topic for the "with" command
```
        ? with
        
```
In the same worksheet as exercise 1:
Assign the Pythagorean Theorem (the sum of x squared and y squared equals z squared) to the variable form
Clear the values of x and z
Assign the Pythagorean Theorem (the sum of x squared and y squared equals z squared) to the variable form

Comment: Notice that the first form has numerical values for x and z squared but the second form is the familiar Theorem that can be used to sub values or manipulated to solve of values of x, y or z.
Use commands to... Assign 10 to x without displaying the evaluated expression
Assign x divided by Pi to x
Find the decimal value (approximation) of x
```
            x := 10:
            x := x/Pi
            evalf(x)
        
```
