## 0. Teacher Appreciation Week

Good teachers are vital for good learning. In many countries, sadly, the teaching profession is not all that highly regarded. One of the reasons I love living in Asia is that teachers here, on the whole, are respected and valued.

This week (2nd to 6th May) is Teacher Appreciation Week. There are many math educators who receive the IntMath Newsletter. Here's wishing you all a great week!

Hint to students: Your teachers really, really appreciate a "thank you" every now and then. This is a good week to do so. š

On with the Newsletter.

Here's something to ponder from the great inventor, Thomas Edison.

If we did all the things we were capable of doing, we would literally astound ourselves. [Thomas Edison]

So please astound yourself in your next math exam! Good luck with it, from IntMath.com.
