Understanding Basic Inequalities

This video tutorial by Mr. J covers how to find solutions to basic inequalities. It explains the concept of inequalities, which are comparisons between two values that are not equal, and introduces the five symbols used to represent them. The video provides four examples, each demonstrating how to determine which values make an inequality true. Through these examples, viewers learn to solve inequalities such as x < 11, 29 ≥ m, y > 13, and 95 ≤ z, with a focus on understanding the conditions that satisfy each inequality.

What is the primary purpose of inequality symbols?

• To subtract two numbers

• To show that two values are equal

• To compare two values that are not equal

• To add two numbers
