Multiplication symbolsThere are three common ways to represent the arithmetic operation of multiplication: (i) by the cross symbol × (often called “times”): (ii) by a dot: (iii) by nothing: The last method is not suitable for raw numerals 0, 1, 2 etc – is generally interpreted as the single number “twentythree” rather than the operation “two times three”. The best multiplication symbol to use for numerals is the cross symbol. If you use a dot with numerals to represent multiplication, make sure you use a centre dot rather than a baseline dot. In LaTeX, it should be formatted with the \cdot command. Do not use the baseline dot for multiplication – that represents a decimal point!!

Re: Multiplication symbolsJaneFairfax, Character is who you are when no one is looking. #3 20090125 16:34:49
Re: Multiplication symbolsIt is also typical for a baseline dot to mean the dot product. But I'm not entirely sure why this is posted in Euler Avenue and not in response to the puzzle... But hey Jane, mistakes happen. Getting angry over something that can't be changed really does nothing but make it worse. "In the real world, this would be a problem. But in mathematics, we can just define a place where this problem doesn't exist. So we'll go ahead and do that now..." #4 20090126 00:04:43
Re: Multiplication symbolsI prefer (2)(3) = 6, typically reserving and for vectors.#5 20130917 18:35:48
Re: Multiplication symbolsWho is the guy who refferenced this in the wikipedia? 'And fun? If maths is fun, then getting a tooth extraction is fun. A viral infection is fun. Rabies shots are fun.'

Re: Multiplication symbolsHi; 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. #7 20130917 23:57:22

Re: Multiplication symbolsI like the center dot given by \cdot best but \times does have its points. 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. #9 20130918 00:59:13

Re: Multiplication symbolsI am sorry, are you asking a question? 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.

Re: Multiplication symbolsI am talking about: http://en.wikipedia.org/wiki/Full_stop#cite_note5 'And fun? If maths is fun, then getting a tooth extraction is fun. A viral infection is fun.

Re: Multiplication symbolsHooahh as the great Al Pacino would say! It does look like they have a link to this site. 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. #13 20130918 01:32:07
Re: Multiplication symbolsand who put that? 'And fun? If maths is fun, then getting a tooth extraction is fun. A viral infection is fun. Rabies shots are fun.'

Re: Multiplication symbolsI do not know who did that. 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. #15 20130918 01:41:47
Re: Multiplication symbolsThe whole thread is kind of stupid 'And fun? If maths is fun, then getting a tooth extraction is fun. A viral infection is fun. Rabies shots are fun.' 'God exists because Mathematics is consistent, and the devil exists because we cannot prove it' 'Who are you to judge everything?' Alokananda #16 20130918 01:44:46
Re: Multiplication symbolsThis one or that one? 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. #17 20130918 01:58:12
Re: Multiplication symbolsThis one. 'And fun? If maths is fun, then getting a tooth extraction is fun. A viral infection is fun. Rabies shots are fun.' 'God exists because Mathematics is consistent, and the devil exists because we cannot prove it' 'Who are you to judge everything?' Alokananda #18 20130918 02:00:55
Re: Multiplication symbolsJudging by what I can see it was an argument in another thread carried over to this one. 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. #19 20130918 02:55:53
Re: Multiplication symbolsWhere is it? 'And fun? If maths is fun, then getting a tooth extraction is fun. A viral infection is fun. Rabies shots are fun.'

Re: Multiplication symbolsI would assume it is in one of ganesh's threads of problems. 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.
