### No End of Right Answers

Thanks to the new LaTeX option in Warwick blogs, I can hint at the clever things assessment software is doing nowadays to seek out deep learning, at least for mathematics.

For an exercise like: "Give an example of a sequence that converges to *e*", it can tell that

and infinitely many more such answers are all correct. Chris Sangwin's brainchild STACK can do this: STACK (System for Teaching and Assessment using a Computer algebra Kernel) is an open-source system for computer-aided assessment in mathematics and related disciplines; it uses the open-source computer algebra system Maxima.

### Blogging Mathematics

My thanks to those who have recently given us the abiility to render mathematics in Warwick blogs.

I can't resist the temptation to try it out. Tradition has it that the phrase "Let no-one ignorant of geometry enter" was inscribed on the door to Plato's academy. For a more modern mathematical motto one might choose Euler's identity:

linking in a surprising manner five fundamental, apparently-unrelated mathematical constants: 0, 1, i, e, and . Hence the in-joke "We are number " sometimes seen on mathematics students' T-shirts.
