maths and fractions

How to create a fraction in a web page? I know only this way: ?. How to get a horizontal line in an elegant way?

Could you, please, suggest a link where to read about it? Thanks. :-)

Hi,

 

You just wrote 1/2 in the post above and ... it looks pretty good to me.

 

 

I suppose you could create a ... around the 1/2 and then use CSS to change the font and text properties. You know, make it bold, all caps etc ....

Hi Stefan,

 

Thank you. It works when we have 1/2 and 1/3. But if I need something like this: a/b + c/d = (a + c)/ d. Or, let's say 2 and 1/3... or 11/4 = 2 3/4 etc ...

You see, this is very nice:

or ∑_i=0^∞

x_i when you need a Sum. But it doesn't work with fractions.

 

 

It's very simple in Word > Object > Microsoft Equation 3.0. I am wondering - do I have to make everything like .gif? Boring.

I hope that there should be something nice, as you said: create a ... around everything.

 

Thanks a lot and Happy Boxing Day!

Create an image for them and reduce to a small size, assuming you haven't got too many.

The proper, semantic way to mark up mathematics is to use....MathML!

 

It is a recommendation of the W3C, and it is certainly the way to go for more complex stuff. Wikipedia has an excellent article with examples here.

 

Predictably, IE only supports MathML with a plugin, so depending on your audience, this may or may not be the best solution.

Thank you, monkeysaurus! MathML looks very good for my task. I've found this page http://www.cs.tut.fi/~jkorpela/math/#fractions, read about it, and I've got completely lost. Now, with your help it looks crystalclear.

You're welcome Accrington. Hope it's useful.

 

And to the HTML zealots here...you need XHTML for this one!

Stefan,

 

Why? They are so cute and so curious. maths and counting sheep...

 

 

monkeysaurus,

 

Thank you once more, even if I do not understand those dots. But it is ok with XHTML. At least I know where to read about it. I hope I will manage MathML for my webpage. Otherwise I could follow Wickham's suggestion.

I would have said that too... but the Monkey beat me!

Place the numerator in a superscript ^{tag and the denominator in a subscript _tag}

2/11

For Forums allowing the sup and sub bbcodes, it would look like this:

 

²/₁₁

 

Not sure if it will work on the new Forum set-up.
