I was a teacher in secondary schools in Australia for some years until I moved to Japan where I taught English and mathematics for 4 years. On returning to Australia, I taught in TAFE, Bond University and Griffith University. (The important word there was “taught” - I was not willing to spend my waking life doing research. Hence…). I moved to Singapore where I taught engineering mathematics. I am now doing staff training.

Hi Zac,

Great website ! I can’t seem to get enough of it and keep coming back for more. Your topics are interesting and diverse. They stimulated my thinking and I enjoyed our discussions. Hope to see more of other topics being posted and others join in our discussions. Cheers!

Vinod’s article is an April Fool’s type piece from BBC:

Computers simply cannot divide by zero. Try it on your calculator and you’ll get an error message.

But Dr Anderson has come up with a theory that proposes a new number - ‘nullity’ - which sits outside the conventional number line.

What is extraordinary to me is the hundreds of people that have commented on the nonsense.

I agree with Matt Milford, who says:

For goodness sake, do NOT teach this to year 10 pupils!

Hi Zac,

I chanced upon your blog in regards to your entry about SMART Interactive Whiteboards.

Would like to touch base with you on that. Do drop me an email when you read this? Thanks heap!

Hi Murray,
I just saw your entry at the sgSocialMediaDir wiki (Individual H-N page). Included additional keywords to describe your blog (you can amend them if you think they are not appropriate).

Fine with me, Ivan - thanks for the better set of keywords! [I edited your comment - by including the link to the wiki.

I loved your Ten Ways to Beat the Math Blues. I’m going to make it required reading for my high schoolers this year. Thanks!

Hi!

I’m teaching Geometry for this few weeks. I’ve been wondering how I can get my hands on a pair of giant compasses that I can use and demonstrate on the board in class.

Can you suggest a way for me to buy one locally in Singapore?

Thanks,
Del

Hi Del. I can see why you had trouble finding a supplier of compasses in Singapore. I’ve just googled like mad and cannot find a supplier.

I expect some of the larger Popular bookstores (like at Jurong East) might have them and Bras Basah Complex has a multitude of related shops and a huge Popular.

The following suppliers (of books, mostly) may know where you can get them:

http://www.sgbox.com/

If all else fails, you could always contact MOE - they would surely know…?

Hi Zac,

I have created a tool to write math equations online. If it is not against your principles, could you put a link on it in your blog?

The URL is http://www.texify.com

Thank you,
Andrey
