of their use in an expression and include the results of the expression.
For example, - finds the difference, for example, 5-3 evaluates to 2.

- Video Game Package
- What is a sprite?

- What are the basic steps in making your own custom sprite?
- Graphics
- What does the monitor resolution describe (i.e. what does 640x480
mean as a monitor resolution)?
- What is a typical monitor refresh rate in Hz (frames per second)?
- For each coordinate system describe the components, possible values
for the components, and what each component describes.
- Cartesian
- Polar
- Screen
- Graphics2D
- When is it a bad idea to represent your graphics using only Screen
coordinates? Give an example of when using Screen coordinates would
cause problems that would not occur using Graphics2D coordinates.
- What is Constructive Area Geometry? Give an example of when
CAG could be useful.

- Which is higher, the Monitor Frame Rate or the Model Frame Rate? Why?
- What happens if the Monitor Frame Rate and Model Frame Rate are too high?
- Video games can be described as simulations. Why are discrete
time approximations often used to describe continous time events?
