# Inequalities

In mathematics, an inequality is a relation between two values when they are different. **Inequality means the condition of being unequal or lack of equality.** Like x < y, x > y,
x $\leq$ y etc. The sign ">" means is greater than, sign "<" means
is less than. In each case the sign opens towards the larger number.**For Example:** 3 < 6 ("3 is less than 6") and 6 > 3 ("6 is greater than 3"). The inequalities can be used for algebraic expressions also. For example: x + 9 < 25 will have all such values of x as solution for whom the the value of the expression (x + 9) will be less than 25.

There are two more symbols in inequality: less than or equal to ($\leq $) and greater than or equal to ($\geq $). If it is given that $x\geq 8$ it will imply that the value of x will be greater than or equal to 8, whereas x > 8 means that the value of x cannot be 8.
