When typing up a reply, is it possible to enter equations without forcing them to start on the next line? i.e. I want to be able to type something like:

"some random reply $$\frac{3}{4}$$ is shown here"

with the fraction 3/4 appearing inline with the text.

Question

When typing up a reply, is it possible to enter equations without forcing them to start on the next line? i.e. I want to be able to type something like:

"some random reply $$\frac{3}{4}$$ is shown here"

with the fraction 3/4 appearing inline with the text.

so the reply should end up something like this:

"some random reply 3/4 is shown here"

anonymous · Answer

I think the openstudy team should enable this option because I have also had such problems(not being able to type the equation in the same line).

asnaseer · Answer

It must be possible because I have seem some people type their replies exactly I want. I just don't know how they did it.

asnaseer · Answer

** exactly as I ...

anonymous · Answer

but I haven't seen any such replies.

anonymous · Answer

yes it's possible look $\frac{1}{2}$ is on the same line!

anonymous · Answer

you need to write  
just single slashes

asnaseer · Answer

let me try $\frac{3}{4}$ - wow! thanks @Thomas

asnaseer · Answer

After more investigation I have also found that in cases where you need a little bit of text in what is mostly an equation you can use \mbox{some text}. For example:
$$\mbox{using }x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\mbox{ leads to }x=1\mbox{ or }2$$

anonymous · Answer

$$\mbox{a}x^2+\mbox{b}x+\mbox{c}=0$$
only x should be emphasized because it's variable :P

First off, you can also use 	ext{}, which is easier to remember. Secondly, a, b, and c should all be italicized in the above. They are all placeholders, despite the fact that they are constants. Only straight text should be non-italicized.
