Is Matrix Subtraction an operation?Is it AB or is it A+(B) ? "The physicists defer only to mathematicians, and the mathematicians defer only to God ..."  Leon M. Lederman #2 20100508 18:11:38
Re: Is Matrix Subtraction an operation?Hi Mathsisfun; 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 20100508 19:10:23
Re: Is Matrix Subtraction an operation?Hi MathIsFun! If two or more thoughts intersect with each other, then there has to be a point. #4 20100509 09:43:05

Re: Is Matrix Subtraction an operation?
Adding a negative and subtraction are different operation that achieve the same thing, so I guess either is okay. The limit operator is just an excuse for doing something you know you can't. “It's the subject that nobody knows anything about that we can all talk about!” ― Richard Feynman “Taking a new step, uttering a new word, is what people fear most.” ― Fyodor Dostoyevsky, Crime and Punishment #8 20120921 11:18:15
Re: Is Matrix Subtraction an operation?Hi MathIsFun! Writing "pretty" math (two dimensional) is easier to read and grasp than LaTex (one dimensional). LaTex is like painting on many strips of paper and then stacking them to see what picture they make.
