Lately, I have received some readers’ request for me to discuss more about SET. This topic used to be in the GCE O level Additional Mathematics syllabus, but has recently made its appearance in Elementary Mathematics (E-Math)
SET itself is yet another way of representation of data, like matrix. Just like matrix, we need to know about the ‘language’ for SET.
Here’s a list of notation which you must be familiar with:
Below is a typical question which requires your translation skills from English to Set Notation:
TIP: Draw a set diagram to illustrate the statements first!

Hi,
I'm Ai Ling. I enjoy coaching students who have challenges with
understanding and scoring in 'O' Level A-Maths and E-Maths. 
Set notation is the easiest for me. It is simple logic, seriously.

If the diagram is not a proper subset, can it still just be a subset?

Be careful that ‘brave’ and ‘smart’ do not make for well-defined sets. One criteria for sets is for them to be well-defined. Otherwise, you risk running into Russell’s paradox.
