Inequality is a relation created between two quantities. It is a method of comparing two values. The two values which are compared are not equal to each other, hence $a \neq b$. There are various symbols which are used to denote the relationship between the two quantities which are being compared. The symbols used are less than represented by ‘$<$’ symbol, greater than represented by ‘$>$’ symbol, less than or equal to denoted by ‘$\leq$’ and greater than or equal to denoted by ‘$\geq$’. When we solve an inequality equation we actually find out the solution of the variable. On plugin the solution of the variable in place of the variable it holds true for the inequality statement being considered.
