You do believe 2+2=4, right?
No I don't believe it, I KNOW it. No faith required here.

And do you know that if a store has 224 dozen eggs, they have 2,688 eggs? How?

And do you know that if a store has 224 dozen eggs, they have 2,688 eggs? How?

By knowing that a "dozen" represents a set of 12, and then either by adding them or by taking the shortcut—multiplying them! Multiplication is just fancy short-hand addition. This particular problem has a real-world counterpart and can actually be proven as a natural fact.
