ELI5: Explain Like I'm 5

Metafunctions

Metafunctions are like superpowers for mathematical equations! They help us understand how equations work together, and they tell us things like if an equation is true or false.

Think of it like this: when you put two numbers together in a calculator, you get an answer. But if you use a metafunction, you can figure out more about that answer, like if it's bigger or smaller than another number, or if it's odd or even.

Metafunctions are like magic spells that we can use to make our equations even more powerful. They're like the superhero cape for math equations!
