MathType and WIRIS Join Forces

A little bit of news for those who, through necessity or ignorance or unique personal whimsy, use a WYSIWYG editor for putting equations into computers.

WIRIS, whose technology is used in things like the virtual learning environment Blackboard, have bought Design Science, makers of MathType. MathType became the de facto standard equation editor for Microsoft Word back before its built-in solution was any good, but has somewhat stagnated recently. The press release says, “by combining our teams we will now be able to offer education, scientific and publishing communities newer products at a fast pace”. I think that’s a long way of saying they’re not going to duplicate their efforts any more.

Do you use mixed fractions?

I’m at the MATRIX conference in Leeds, where I’ve just been talking to Adam Atkinson. He told me that he’s trying to compile a definitive list of countries that don’t use mixed fractions.

Here’s a mixed fraction: \[ 2 \frac{2}{3} \]
And here’s a non-mixed fraction: \[ \frac{8}{3} \]
Actually, here’s an interesting fact about that number: \[ 2 \sqrt{ \frac{2}{3} } = \sqrt{ 2 \frac{2}{3} } \]
This only makes sense if you believe in mixed fractions (and unicode character U+2062, “invisible times”)

This is going to be one of those wipe-your-bum-standing-up situations: it’s entirely possible that you can be on either side of this divide and not know the other exists. Apparently, in some countries mixed fractions just don’t exist: an integer written next to a fraction is incorrect.

So, to help Adam on his way, I thought I’d start another in our long-running series of Aperiodical Surveys. Please tell us where you live, and if mixed fractions are OK in your book.
