Today we learn more about the classification of numbers (rational / irrational), and we describe the relationship between these number sets with our previous number sets using a venn diagram. You finally learn about the set builder notation which will help you define your own number sets.
In this lesson we talk about how to play sound effects in your game whenever you shoot a missile or whenever an enemy explodes.
In this lesson we talk about the classification of numbers into different sets called natural numbers, whole numbers, integers, and real numbers. We will investigate deeper into this matter next lesson.

In this lesson we fix the bug where the enemies and your spaceship move off the screen boundary. We also make it so when enemies collide with your missiles, they reset back to the top with a random x coordinate.
In this video we introduce you to Venn Diagrams, an important concept in set theory. We also talk about how to put some real life information into a venn diagram. We will talk more about how the venn diagram relates to set theory in the next lesson.
In this lesson we design some random movements for the enemies as they come downwards at the spaceship randomly moving left and right.
