Let us use this procedure to solve inequalities of different types. But to solve any other complex inequality, we have to use the following process. The process of solving inequalities mentioned above works for a simple linear inequality. Why? This is because we have multiplied both sides of the inequality by a negative number.

Step - 7: Intervals that are satisfied are the solutions.īut for solving simple inequalities (linear), we usually apply algebraic operations like addition, subtraction, multiplication, and division.

Step - 6: Take a random number from each interval, substitute it in the inequality and check whether the inequality is satisfied.

Step - 4: Also, represent all excluded values on the number line using open circles.

Step - 3: Represent all the values on the number line.

Step - 2: Solve the equation for one or more values.

Step - 1: Write the inequality as an equation.

Here are the steps for solving inequalities: Multiplication or dividing both sides by a negative number Multiplying or dividing both sides by a positive number Operation Applied While Solving Inequalities The rules of inequalities are summarized in the following table.

Taking a square root will not change the inequality. Putting minuses in front of p and q changes the direction of the inequality.Ī square of a number is always greater than or equal to zero p 2 ≥ 0.Įxample: (4) 2= 16, (−4) 2 = 16, (0) 2 = 0 Inequalities Rule 8 Positive case example: Oggy's score of 5 is lower than Mia's score of 9 (p −q. If you multiply both p and q by a negative number, the inequality swaps: p qd (inequality swaps) If you multiply numbers p and q by a positive number, there is no change in inequality. So, the addition and subtraction of the same value to both p and q will not change the inequality. Inequalities Rule 3Īdding the number d to both sides of inequality: If p q, then p + d > q + d, and Inequalities Rule 2Įxample: Oggy is older than Mia, so Mia is younger than Oggy. When inequalities are linked up you can jump over the middle inequality.Įxample: If Oggy is older than Mia and Mia is older than Cherry, then Oggy must be older than Cherry. Here are some listed with inequalities examples. There are different types of inequalities. p ≥ q means that p is greater than or equal to q.p ≤ q means that p is less than or equal to q.One of the things may be less than, greater than, less than or equal to, or greater than or equal to the other things. The meaning of inequality is to say that two things are NOT equal. This is a practical scenario related to inequalities.

But you do know her age should be less than or equal to 12, so it can be written as Olivia's Age ≤ 12. How old is Olivia? You don't know the age of Olivia, because it doesn't say "equals". The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign. In inequality, unlike in equations, we compare two values. Inequalities are the mathematical expressions in which both sides are not equal.
