What is meant by 'cardinal value' in the context of notation?

In simple terms, a cardinal value tells us "how many" of something there are. It shows the quantity or size of a group or set, without worrying about the order.

For example:

If you have a basket of 5 apples, the cardinal value is 5 because that's how many apples there are.

In the context of notation, especially in math or set theory, a cardinal value is used to represent the number of elements in a set.

Example:

Set A = {2, 4, 6}

The cardinal value of Set A is 3 (since there are 3 elements)

Cardinal value = total count or quantity of items in a set (not their position or type).
