The video tutorial introduces the concept of inequalities in mathematics, explaining their meaning and how they differ from equalities. It covers the use of inequality symbols, such as greater than and less than, and demonstrates how to express real-world scenarios as mathematical inequalities. The tutorial also includes instructions on graphing inequalities on a number line and provides practice problems for learners to apply their knowledge. The video concludes with additional resources for further practice.

What does it mean when two things are not equal in mathematics?

• They are equal in all aspects.

• They are identical.

• They are different in value.

• They are the same in size.

Which symbol represents 'greater than' in inequalities?

• ≥

How can you remember which number goes on the open end of the greater than symbol?

• The larger number goes on the open end.

• The numbers are equal on both ends.

• The open end is always on the left.

• The smaller number goes on the open end.
