When I was a kid I learned all kinds of math. The older I got the harder the math became. Sometimes with other things I could get the hard stuff out of the way first and then do the easy stuff, so I wished that with math I could do the hard stuff first so that it got easier as I went along.
Unfortunately if you can’t do the easier, simpler stuff in math you won’t have any clue how to do the harder stuff. In this I learned a life lesson. Sometimes you have to build a base doing the simpler stuff first, or you’ll never get to the hard stuff. If you have the basics down, it makes the hard stuff a lot less difficult.
