One operation at a time? What is 10/5 ? How about [imath]3^2[/imath] ?My calculator says 25, but I'm baffled how you work this out in your head.
Here's an introduction to the ideas involved:Hi
I'm revisiting my GCSEs in my 40s and I'm doing okay, but there's one question I can't get my head around;

Any help would be much appreciated.
