When I was studying math in elementary school and high school, I had no idea that what I was actually studying was only a tiny bit of a diverse field filled with science, knowledge, and art.
It was like looking at a rainbow where the only light you see is what you are capable of seeing, but in reality, you are only witnessing a tiny bit of a much more majestic view - a larger spectrum of light that is hidden until you get the right equipment so to speak.
It’s the same with math. They feed you with what they think you are capable of understanding and hide the good stuff for when they think you are ready!
