# Which character to use to activate MathJax?

We were offered to get MathJax enabled.

Now, we need to decide on which character to have text between them parsed into MathJax! So please either add your suggestion or cast your vote!

Let's stay with the classic $. Example: \$\$\frac{1 \times 2}{2} = 1\$\$Now that MathJax is enabled, it renders to: $$\frac{1 \times 2}{2} = 1$$ • Yes, classic please ($ and ) – Greenonline Sep 6 '18 at 11:27
• This should be the accepted answer, the majority has ruled! :) – 0scar Sep 9 '18 at 13:23

An alternative character could be the Tilde ~.

• We should stay consistent with other sites. Robotics uses $, and maybe Mathematics – Greenonline Sep 6 '18 at 11:28 • @Greenonline That is a very good reason to go for$, I wonder which character is used by other sites that have MathJax enabled. – 0scar Sep 6 '18 at 11:39
• Just checked on Robotics, and a $on its own is rendered correctly, so I cant see a problem. – Greenonline Sep 6 '18 at 11:45 • Math and RPG use$ – Trish Sep 6 '18 at 11:55

Dollar works in isolation. See:

However, two (seemingly unrelated) dollar signs will cause a problem, see Weird behaviour when using two (2) $signs?, such as this: * Build a$1 Billion home ([Mukesh Ambani](https://en.wikipedia.org/wiki/Antilia_(building)))
* Build a $1.2 Billion Yacht ([Roman Abramovich](https://en.wikipedia.org/wiki/Eclipse_(yacht)))  • You can even have$ as part of the equation. Existing posts can potentially become broken, I think that is the only risk. Clearly, they can be edited as soon as we find them. – Sean Houlihane Sep 6 '18 at 12:18
