In this video, we enter the world of inequalities. We discuss what OR and AND have to do with inequalities - how they make slack and double inequalities. We then categorise inequalities into different groups - Numerical and Literal inequalities, Strict and slack inequalities, Inequalities with one and two variables, Linear and quadratic inequalities. We finally look at the formal definition of linear inequalities.

Except when we are multiplying or dividing by negative numbers. What happens in that case? Why does it happen? Let's learn all about it in this video and practice what we learn on numerical and literal inequalities.
