Small question on inequalities!Hey! #2 20121116 08:50:59
Re: Small question on inequalities!Hi BarandaMan; In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #3 20121116 08:54:09
Re: Small question on inequalities!Really?! #4 20121116 08:56:54
Re: Small question on inequalities!hi BarandaMan x by 5 Add 2z take 6 divide by 2 I suspect you ran into difficulty because of this take 2 divide by 2 when you multiply or divide by a negative amount you must reverse the inequality sign Bob If you want to explore this rule some more, post back. hi bobbym, sorry didn't know you were posting too.

Re: Small question on inequalities!Thank you very very much indeed. The change of the inequality sign is what got me. Thank you for helping me. #7 20121116 09:15:14

Re: Small question on inequalities!Wow, this is incredible. Thank you really. I don't know why people don't get taught stuff like this sometimes, or maybe I forgot, but never the underlying reasons for the rules it seems. This actually makes sense. Thank you. I don't think I will forget it again. I drew it out with three examples!!
