the link to math exercises doesn't work

[Elizaveta Serdtseva]

The Purgatorio -> Fundamentals -> Linear Algebra section contains a link to exercises and this link doesn't work.

Check your knowledge

Test your knowledge with these exercises.

Anyway you can find a ton of them online, and remember, that the more you practise, the better you will get!

Could it be deleted or replaced with other materials, since there are lots of them on the internet?

Thanks a lot, working on it
