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!
