The marvel of Math is in its non-obviousness. Obvious truths are not marvelous but non-obvious ones are.
"Magic" is also a word we can use about Math because we know no true magic exists. Therefore when something is said to be "magic" we know it means something "looks like magic".
For the Magician (/Mathematician) it of course doesn't look like magic because they clearly understand and see how it works.
So, you are perhaps the Mathematician/Magician for whom it doesn't look like magic but for the rest of many of us it does. We are even willing to pay for the ticket to see magicians perform their "magic" and to marvel at it.
