## Lab Steps

- Open this file in Firefox and Microsoft Visual Studio
- Add your name, section, and email
- Add code after the line: `YOUR CODE STARTS AFTER THIS LINE:` to complete this lab.
- Your output should look like the Example Output below.
- Variable declarations section
  1. Write a comment that identifies this coding section.
  2. Add the following variables:
     1. `results1`
     2. `results2`
     3. `results3`
     4. `results4`
     5. `results5`
     6. `results6`
     7. `results7`
     8. `results8`
     9. `results9`
     10. `results10`
- Assignments section
  1. No assignments section this time! They will get values in the calculations section.
- Calculations section
  1. Write a comment that identifies this coding section.
  2. Perform the following calculations and assign the results to the corresponding "numberx" variable. The calculated value must be what is indicated after each step. Add parentheses to get the correct results.
  3. Here's how to do the first one:
     1. `results1 = (25 * 10) / 2;`
  4. The calculations:
     1. `25 * 10 / 2 --> 125`
     2. `3 + 4 * 5 --> 23`
     3. `3 + 4 * 5 --> 35`
     4. `1 + 2 + 3 - 4 + 5 --> 7`
     5. `1 + 2 + 3 - 4 + 5 --> -3`
     6. `20 * 10 / 2 --> 100`
     7. `2 / 3 * 3 * 3 --> 6`
     8. `2 / 3 * 3 * 3 --> 0.666666666666667`
     9. `2 / 3 * 3 * 3 --> 0.0740740740740741`
     10. `2 * 2 - 2 --> 0`
- Output section
  1. Write a comment that identifies this coding section.
  2. Use a `document.write();` to output the results. Add the calculation and the parentheses to the output. Here's how to do the first one:
     1. `document.write("(25 * 10) / 2 --> " + results1 + "<br />");`

- Note: Add parentheses to each calculation, even if they don't change the value.

### Example Output

- Without the parentheses that make it work.

    25 * 10 / 2 --> 125
    3 + 4 * 5 --> 23
    3 + 4 * 5 --> 35
    1 + 2 + 3 - 4 + 5 --> 7
    1 + 2 + 3 - 4 + 5 --> -3
    20 * 10 / 2 --> 100
    2 / 3 * 3 * 3 --> 6
    2 / 3 * 3 * 3 --> 0.6666666666666666
    2 / 3 * 3 * 3 --> 0.07407407407407407
    2 * 2 - 2 --> 0
