what's the mean of a set as element of another set? give me explanation about that...

The answer:

If an entire set is contained within another set, it is called a SUBSET.

For example, suppose set A contains only three numbers: 1, 2, and 3

In set notation:

A = {1,2,3}

Now suppose set B contains ten numbers: 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9

In set notation:

B = {0,1,2,3,4,5,6,7,8,9}

Set B contains more numbers than set A, but ALL OF THE NUMBERS IN SET A are CONTAINED IN SET B

A is a SUBSET of B

This is written using the ⊂ symbol. (You can type this symbol on your computer by holding down the ALT key, typing 8834, then releasing the ALT key.)

A is a SUBSET of B

A ⊂ B
