Why Are Some Numbers Magical and Others Just Plain?

Some numbers feel magical because they show up in weird places, like why there are 7 days in a week or how pies taste so good. Think of the number seven like your favorite toy that works no matter what you do with it. Numbers like π also appear everywhere, even when we don’t expect them to!
