### Question Description

Help me study for my Mathematics class. I’m stuck and don’t understand.

1. What is a Set?  Give an example
2. When are two sets equal?  Give an example of two equal sets
3. What is the empty set?  Give an example Student has agreed that all tutoring, explanations, and answers provided by the tutor will be used to help in the learning process and in accordance with Studypool's honor code & terms of service. Set's are just numbers. It is a set of numbers. You use this bracket: {} But it's just a set of numbers.

An example of a set is {1,2,3,4}  That set has 4 numbers.

Two sets are equal if they have the exact same numbers. The numbers don't have to be in the same order, but they must be the same. Example:

{1,2,3,4}  and {3,2,1,4}  These set's are equal. They have the same numbers in them.

An empty set has no numbers in it at all:

{}  Nothing going on there.

But empty set's are subsets of all set's.

Subsets are a different subject. If you need help understanding it, let me know. Doctor T (547)
