welcome to mistreil's perfect(?) math class!
This first lemma is as easy as 1 + 2,
For you see, we're talking about red + blue
The answer is simple: it's the colour purple
The team that'll be in the victory circle!
Lemma #2 relies on evidence corroborative,
Which leads us to know that red and blue are both positive.
The result we can conclude from lemma 1 and lemma 2,
Is that red is less than purple, and purple is greater than blue!
As for green, the unmentioned team,
Its placement in this is left to be seen.
But if green is the sum of both yellow + blue,
Then maybe blue is what green is equal to?
