Assignments , case studies and revision papers are the best way to teach someone

I am a mining engineer. I dealt with different types of math subjects throughout my course. I have an A for Cambridge IGCSE mathematics which I acquired in Botswana. I was once a tutor during my time at Namibia university of science and technology, which was not limited to mathematics but also mathematic related subjects like numerical methods and physics so basically I’m good with formulae. I worked as a mine surveyor at twiga cement where I dealt with mathematical formulas which was mostly on excel but it gave me a broadened mindset on the subject and I feel like I can extend my knowledge to peers and people younger than me
