Inequality Symbols (Part 1)

The video tutorial explains the concept of equations and inequalities, highlighting the difference between equal and unequal expressions. It introduces five main inequality symbols: greater than, less than, greater than or equal to, less than or equal to, and not equal. The tutorial emphasizes the orientation of inequality symbols, where the larger end faces the larger number. Each symbol is explained with examples, illustrating their use in comparing numbers.
