# Writing Dollar Signs on Octopress Blogs With MathJax Support

When I was writing my previous post, I typed three $ in one single paragraph. Although I’d tried adding \ in front of $1, part of the words between $ are still parsed by MathJax. ## Solution According to another page in MathJax’s official documentation, this problem can be solved by surrounding the dollar sign by a span tag with class tex2jax_ignore2, i.e. <span class="tex2jax_ignore">$</span>.
