I can't say I love math. I'm actually pretty good at math concepts. But I make transposition mistakes ALL.THE.TIME.Thanks for fixing it. I'm not an expert in what I was attempting to explain, therefore it makes it hard to translate what is in my head, to something understandable on paper. As much as I love math, and I do, I was never any good at it.
What @DeeAnna said helps me a lot: keep the measuring units consistent, whether that is ounces, grams, percentages, or my favorite generic favorite, "parts." So I would say: 3 parts each of thio and metab, to 10 part water.
