ProportionI just have a little problem : #2 20130203 05:26:06
Re: ProportionWhen you multiply by 7 you cancel the 7 on the left but not the 9 on bottom right. 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 20130203 05:30:18
