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 Ong. I enjoy coaching students who have challenges with understanding and scoring in 'O' Level A-Maths and E-Maths. I develop Math strategies, sometimes ridiculous ideas to help students in understanding abstract concepts the fast and memorable way. I write this blog to share with you the stuff I teach in my class, the common mistakes my students made, the 'way' to think, analyze... If you have found this blog post useful, please share it with your friends. I will really appreciate it! :)
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.
this information was really helpful :0
