Summary
No video gets me more email from students! How few colors can you use to color in any map so that no two, neighboring regions are the same color?
- First, we introduce the idea of coloring in regions on a map with a very simple example that needs only three colors.
- Then, we increase the challenge a bit with a second map that still only needs three colors.
- Next, we present an even more challenging map.
- We reveal the coloring problem's true solution: no map needs more than four colors.
