Config ({ extensions : [ "tex2jax.js" , "TeX/AMSmath.js" , "TeX/AMSsymbols.js" ], jax : [ "input/TeX" , "output/HTML-CSS" ], tex2jax : { inlineMath : [ [ '$' , '$' ], [ "\\(" , "\\)" ] ], displayMath : [ [ '$$' , '$$' ], [ "\\[" , "\\]" ] ], }, "HTML-CSS" : { availableFonts : [ "TeX" ] } }); </script> after the header ( <head> ) in the Blogger template.
