Answer the following questions:

Be sure to provide screenshots along with your explanations.

1. Include a screenshot of an interesting design that your Logo app made and a screenshot of the code that created it. Press the power button and volume down at the same time to take a screenshot.

Include this image and code in your write-up document, below.

The lesson here is that our choice of abstractions, in this case the use of parameters in our Logo commands, affects the kinds of problems we can solve and how we solve them. That is, our choice of abstractions have an enormous impact on our algorithms. In addition, procedural abstraction (both with and without parameters) makes algorithms easier by raising the level of abstraction.

2. Describe in your own words, with a specific example from Logo, how our choice of abstractions (commands) in this lesson provides us with the ability to solve problems that couldn't be solved with the abstractions (commands) used in Logo Part 1.

Answer

The abstractions that we use in logo 2 are more complex because we have the ability to define variables in our procedures. A variable is a n abstraction, and when placed inside of a procedure, it is an abstraction inside of an abstraction. The ability to use variables allows us to define the shape that we want to make and the side length of the shape, something that we could not do in logo1, where we had to make procedures for going foreward by 0 or 40.
