Welcome to a new post where, I have to admit, I’d forgotten what I’d written in a previous one!

In Mathematics Question – Number 15 and beyond! I’d said:

“From *Mathematics Question – Number 17*, onwards, I plan to post each question on the blog, as well, with extra comments that will then appear in the *Mathematics Questions – Newsletters*. So, basically, each question, plus comments, will become part of the blog and then the newsletter will appear periodically, bringing together, each time, three questions plus comments (as it does now). Hope that makes sense!”

The above didn’t materialise! Oops! What will happen is, I will be publishing the questions as normal on my website, nilsbirdtraining.com/mathematics-resources, and then the newsletter will be published in this blog.

So, here goes with **Mathematics Questions – Newsletter No. 5**.
