OK, its 4:30 in the morning, and I am working on my liquid soap. I am brain fried, and having the soap of a time trying to remember how to get the % of something correct. Math was never my strongest suit, and I had always had to struggle here anyway. So.. for example, I want 1% of 16 ounces. Is that 16 x .01 OR is it 16 x 1% OR 16. x .1 OR 16 x .1% (using a calculator of course... lol). Cause you get a different answer... Seems if you utilize the % key on the calculator instead of just doing it w/o it, the answer come up differently... Told you I was brain fried!
