I’m guessing most of you have heard that the lottery is a tax on people who are bad at math. When it comes to gambling, there aren’t many games where reward to risk is less than the lottery.
But alas, I don’t want to talk about gambling today. I want to talk about pizza. I said it before, and I’ll say it again. Nerds love pizza. Probably even more than Jolt Cola or Mountain Dew. So what does this have to do with math? Well there is a pizza-tax being imposed on the mathematically challenged, and I’m here to call it out.
I stopped by Domino’s last night, because the billboard out front declared that they had “Large Pepperoni Pizza” for $4.99. No, that isn’t a typo. As much as I prefer the pizza from a small local restaurant over any of the local chain stores, I will eat a chain-store pizza…if the price is right. They called it the “Big Deal.”
$4.99 was definitely the right price, even less expensive than the Little Caesar’s special which resembles a Freschetta frozen pizza.
Back to the math—when I received my 10-slice *large* pizza, I was a little perplexed that the box was a rectangle, and seemed smaller than the usual Dominos large box. I had already paid for it, and I was too hungry to debate, so I took the pie home and knew I needed to assess what I just bought.
Using a little math, I decided to compare the size of my pizza pie to the traditional pies you get at a chain store. Here are the measurements and approximate surface areas of “Traditional Round Pizzas”:

As you can see, each size is progressively bigger than the last, and if we desired, we could compare value easy. A large is roughly twice the surface area of a small, so if you can buy two small pizzas for less than a large costs, you should consider it.
Now let’s assess Domino’s 10 Slice Large “Big Deal”:

Perspective is a little off due to the camera lens. Actual measurement corner-to-corner was slightly over 14 inches. And remember, this is a comparison of size, not taste.
So how does the *Big Deal* measure up?

There you have it. Slightly bigger than a small. A true disappointment.
12% more toppings, and 24% more crust than a small. Pathetic. I suppose if you prefer crust to toppings, this might not be all bad news, as there is more circumference to a rectangle, than a circle with the same surface area. For me though, as good as the crust is (it’s brushed with garlic butter), I’d prefer a better value.
So Domino’s, go ahead and keep selling the *Big Deal* if you must. It isn’t even a bad-tasting pizza, as far as chain-store pizzas go. But stop calling it a “Large Pizza,” please?
It’s okay if your pi r-squared, (gratuitous nerd humor) but I prefer my pizza round. That way I can quickly determine if you are trying to charge me the “tax reserved for people who are bad at math.”
