I think you've missed the point of the question Terry. I suggest that 
you re-read the whole question... Christina's message effectively 
changed the topic; we aren't talking about how to interpret % solution 
strengths anymore, and we definitely aren't talking about the simplicity 
or complexity of manuals...

If you want to do something, with also understanding what you are doing, 
you MAY actually need a little more knowledge than what is provided in 
the manuals ect. "Stoichiometry" is a chemistry term which can be looked 
up in the web, and there are many simple (to someone that had their 
Chemistry 101 class) explanations present. Since we are dealing with raw 
chemicals and do chemical / photochemical reactions while working, I 
think we need some - minimum - compulsory chemistry knowledge. If, not 
we risk to harm ourselves and/or others...

If a single person in this list will lookup for the term "stoichiometry" 
in the web, after my "pointy hat" behaviour of using it "at this level" 
(What you're taking us for, BTW?), to me that means I've done good...

I'm not even try to argue with you on how much math is important in many 
aspects of life (including art), let alone in our currently technical 
context. People should've been loving it instead of intimidating by math...

See the book: "The Art of Mathematics" by Jerry P. King for a good 
account on the issue and many more eye opening information:

This kind of jargon does not impress.  It reminds me of the prospective platinum printer who told me that he had decided, after reading a well known manual on the subject, that he had decided not to take up platinum printing as he did not understand the maths!  Of course all the maths in the manual were quite unnecessary in the making of good platinum prints.
