2 pizzas are better than one, right? Not necessarily.
One 18" pizza is more pizza than 2 12" pizzas. That's one major mind blowing knowledge drop. It doesn't seem possible.
But 2 pizzas?
For most of us, this demands a certain amount of trust in math. It's like a kid has to trust that a dime is more than a nickel, even though it's smaller. Wait, bad example. More confused.
The only way this pizza equation doesn't satisfy... is if you're a crust lover.
Confused? Don't be.
Like pizza? Get the 18"
Like crust? Get the two 12".
