如何显示jqmath中的删除线？

Question

For example I want to show reduction of fractions to simplest terms by doing prime factorization on numerator and denominator and then showing common terms that can be eliminated.

So something like $6/8=(2)(3)/(2)(2)(2)=3/4$ but showing a strikethrough on the 2s on the top and bottom.

Answer 1

Basically you use CSS, like in jqMath highlight box like bbox in MathJax/MathJs . So write eg $$6/8={\\cl"cancel"{(2)}(3)}/{\\cl"cancel"{(2)}(2)(2)}=3/4$$ and then add .cancel { text-decoration: line-through } to your style sheet.
