## Why do you flip the inequality sign when multiplying by a negative number?

When you multiply both sides by a negative value you make the side that is greater have a “bigger” negative number, which actually means it is now less than the other side! This is why you must flip the sign whenever you multiply by a negative number.

## Do you have to flip the sign if you multiply by a negative?

Flip the inequality sign when you multiply or divide both sides of an inequality by a negative number. You also often need to flip the inequality sign when solving inequalities with absolute values.

**What is the rule for flipping inequality signs?**

Anytime you multiply or divide both sides of the inequality, you must “flip” or change the direction of the inequality sign. This means that if you had a less than sign <, it would become a greater than sign >.

**Why does multiplying two negatives make a positive?**

Each number has an “additive inverse” associated to it (a sort of “opposite” number), which when added to the original number gives zero. The fact that the product of two negatives is a positive is therefore related to the fact that the inverse of the inverse of a positive number is that positive number back again.

### When solving inequalities You Must the inequality when by a negative?

Whenever you multiply or divide an inequality by a negative number, you must flip the inequality sign.

### What happens to the direction of the inequality symbol if we multiply divide same negative number to both sides of the inequality?

If both sides of an inequality are multiplied or divided by the same positive value, the resulting inequality is true. If both sides are multiplied or divided by the same negative value, the direction of the inequality changes.

**Do two negatives make a negative?**

Two negatives cancel each other out. It’s a negative. “Don’t not do it” means “please do it”. Two negatives cancel out and make a positive, in maths as well as in speech.

**Can you multiply inequalities?**

There is one very important exception to the rule that multiplying or dividing an inequality is the same as multiplying or dividing an equation. Whenever you multiply or divide an inequality by a negative number, you must flip the inequality sign.

#### Does the inequality sign change when you multiply by a negative?

You only change the inequality sign if you divide or multiply both sides by a negative number. Thus, if you divide or multiply both sides by a positive number,the inequality sign will not change. Have any Question?

#### How do you solve inequalities with negative numbers?

Let’s try another example of solving inequalities with negatives. Anytime you multiply or divide both sides of the inequality, you must “flip” or change the direction of the inequality sign. Solve the inequality. Subtract 4 4 4 from both sides.

**What are the rules for multiplying and dividing inequalities?**

There is one very important exception to the rule that multiplying or dividing an inequality is the same as multiplying or dividing an equation. Whenever you multiply or divide an inequality by a negative number, you must flip the inequality sign. Subsequently, question is, what are the rules for solving inequalities?

**When should I flip the inequality sign?**

Flip the inequality sign when you multiply or divide both sides of an inequality by a negative number. You also often need to flip the inequality sign when solving inequalities with absolute values.
