Add some definitions of your own in the definitions area. Be sure to click Run again before you try testing them out.
In today's teaching video, we practiced entering functions to see what they produced. One of
the functions created a transformation of the star. What function was used to create a transformation that changed the size of the star?

Let's work through the questions and tasks you've mentioned.
1. **Testing Expressions**: In the Interactions Area, you can test the following expressions one by one. Before running them, consider what each expression should evaluate to:
- `x`: This will return the value of x if it has been defined.
- `x + 5`: This will add 5 to the value of x.
- `y - 9`: This will subtract 9 from the value of y.
- `x * y`: This will multiply the values of x and y.
- `z`: This will return the value of z if it has been defined.
- `t`: This will return the value of t if it has been defined.
- `gold-star`: This will return the value of gold-star if it has been defined.
- `my-name`: This will return the value of my-name if it has been defined.
- `swamp`: This will return the value of swamp if it has been defined.
- `c`: This will return the value of c if it has been defined.
- `x * y`: This will be the same as above; you'll check the multiplication result again.
After you enter and test these expressions, you will see their respective output based on the definitions provided beforehand.
2. **Adding Definitions**: You usually need to add definitions in the definitions area before testing them out. For instance:
```pyret
x = 3
y = 10
z = 5
t = 8
gold-star = "⭐"
my-name = "Your Name"
swamp = "Wetland"
c = 7
```
Don't forget to click 'Run' after adding these definitions to evaluate them.
3. **Transformation of the Star**: In your teaching video, the transformation that changed the size of the star was most likely done using a scaling function. In many programming contexts, this would simply be referred to as "scale" for resizing or "resize". Depending on the specific programming constructs used in Pyret, it could be "scale".
If you have more specific values or functions defined, please make sure to use those while testing. Once you've done these tasks, you should have a solid understanding of working in code.pyret.org. If you need any further assistance or specific coding examples, feel free to ask!
