Simon finished up the last problem on his math homework and put it in his folder.
"Pi, I don't know what I would do without you."
"Pie?!" Theodore exclaimed as he peeped his head into his bedroom. "Simon, are you saying you have pie?"
"If you mean a pie as in the dessert, then no. I was talking about the number pi, spelled P-I. It helps me find the circumference or the area of a circle."
"Oh," muttered Theodore disappointingly.
"Pi is actually really helpful, especially in my advanced math classes. Did you know that there are a lot of digits with it? It starts as 3.14…"
Theodore let his brother continue listing numbers. If he was ever through with it, he was going to make a delicious pie himself.
