The Abstract Algebra of Direct Proportions
Hello mathematicians, puzzlers, and other curious people! This post previously appeared in the Mathematical Musings free class on Teachable, currently available in the Teachable archive. In a previous MMusing, I mentioned a rabbit trail upon the occasion of using the word \”group\” about functions in the form f(x)=kx, called direct proportions. I didn\’t run down…
Direct Proportions
Hello mathematicians, puzzlers, and other curious people! I mentioned a rabbit trail in a previous MMusing, when I used the word \”group\” about functions in the form f(x)=kx, called direct proportions. I didn\’t run down that rabbit trail that day. Let\’s do it today. In ordinary English, a group is any collection of things —…
