A loop is created like this: imagine you draw three segments as if partially going around a rectangle. a is the first side, turn left, b is the next, turn left, and then c. At this point though, turn left and go a units again... You can also try the instructions here: https://recipesforpi.files.wordpress.com/2015/09/loops.png
In this case, I set a=8 and b=5. Then let c run through every integer from 3 to 13, for reasons of curiosity. I noticed a few interesting things... can you see them? Use the checkboxes to help you investigate.
