Understanding Inequalities: Multiple Solutions Explained with a Number Line

The video tutorial explains the concept of inequalities, highlighting that they are mathematical sentences indicating that two amounts are not equal. It covers the five inequality symbols and clarifies common misunderstandings about them. A real-world example involving marbles is used to demonstrate how inequalities can have multiple solutions. The tutorial shows how to solve inequalities using substitution and a number line, emphasizing that as long as the sum is less than a given number, it is a valid solution. The lesson concludes by reinforcing the idea that inequalities can have multiple solutions.
