That is a math concept that is lost on many people. It is lost on engineers who should be good at math.
Many years ago I was given the opportunity to teach a very basic math refresher style math class in a for profit community college setting. It was very interesting to me as I have an engineering background and my math abilities are strong. I began to think deeply about “Why is this easy for me and hard for these students?” I used that as a mantra when I was trying to explain and help them through the class. My other duties where chief GED instructor. There I discovered that if you can read well, all else is easy (maybe not exactly easy but at least attainable with time).
This was an eye opening experience. One of the forks in my life journey was accept a job in industry or continue my education and teach on the university level. I chose industry and never looked back but teaching these couple classes as an adjunct wizard taught me much about myself and what is important.
Order of Operations is important in math.
Many other things are important in life.
Carpe Diem.
