Students often ask me about the difference between ‘either’ and ‘neither’ and it normally results in me drawing a table on the board. I finally put this into a document and thought I would share it in case anyone else finds it useful.
(You can download it by clicking ‘slideshare’ and logging in – it’s free to create an account, and you can link via facebook if you want to.)
Let me know if there’s anything you think I should add/change to improve it.
