While I don't see this site needing to express a lot of equations, I can see where we're going to have a lot of use of fractions and numbers with associated units.
For example, all of the quarter and octal (?) fractions are frequently used in measurements. Dropping into 16ths, 32nds, and 64ths is common as well.
Having MathJax enabled will make it easier for us to indicate those dimensions.
So can we have MathJax turned on for Woodworking, please?
