Putting fractions and exponents in comments on this blog

Cool thing, if you like: you can make real-looking fractions and exponents on this blog.

The key is something called LaTeX, a special language for laying out text. WordPress blogs can handle a version of LaTeX.

How to start/how to end

you’ll need a dollar sign immediately followed by the word “latex” to start, and a dollar sign to end

fractions

type:  \frac{num}{den}

You need the slash, no space, the letters f-r-a-c, and then two sets of curly brackets, no spaces, with the numerator in the first set, and the denominator in the second

exponents

type: base^{exp}  or just y^x if the exponent is one digit or variable

examples

I am using S instead of $, so you can see

Slatex \frac{5}{6a} S  becomes

Slatex 3^{2x} + 3^x S becomes

Slatex e^{i\pi} – 1 = 0 S becomes
