Frequently Asked Questions (FAQ)
  • What are the 4 inequalities?
  • There are four types of inequalities: greater than, less than, greater than or equal to, and less than or equal to.
  • What is a inequality in math?
  • In math, inequality represents the relative size or order of two values.
  • How do you solve inequalities?
  • To solve inequalities, isolate the variable on one side of the inequality, If you multiply or divide both sides by a negative number, flip the direction of the inequality.
  • What are the 2 rules of inequalities?
  • The two rules of inequalities are: If the same quantity is added to or subtracted from both sides of an inequality, the inequality remains true. If both sides of an inequality are multiplied or divided by the same positive quantity, the inequality remains true. If we multiply or divide both sides of an inequality by the same negative number, we must flip the direction of the inequality to maintain its truth.
