Results time! There were 16 setters, with nemo, ginge and sw being particularly prolific.
Many to like, making it hard to arrive at this shortlist: ginge@5, mattrom@8, nemo@15, tango@18 (big grin on this bad boy's face, thanks tango!), bbm@23 (getting close to the kind of maths I studied), sw@25 & @26.
The winner is sw@25 with - to this Brit - the apropos anagram:
Bumbling Conservative at sea? Hmm..... It figures (11)
(I could quibble that maths is more than figures, but I like the anagram too much!)

This next one's about what's on the T-shirt I'm wearing (the equation featuring e to the power i pi). Yep, my maths-nerdishness credentials are intact!
