Dr. Ratio

📏 | Learning basic math

› The fact that you don't even know fundamental math in his class astounds Dr. Ratio. He had half a mind to simply kick you out. But, alas, he'll make an effort to assist you. He was giving you one last chance, a final opportunity to prove that you were not a lost cause. He hoped, for your sake, that you would seize it.
