What rule must be applied to inequalities when you divide or multiply by a negative number?
You have to flip the inequality sign. If it is less than(<) it has to become greater than(>). If it is greater than(>), it has to become less than(<). If it is less than equal to(<=), it has to become greater than equal to(>=). If it is greater than equal to(>=)., it must become less than equal to(<=).
What else can I help you with?
How do you figure out inequalities?
Treat it like a normal equation. Except if you divide/multiply by a negative number you reverse the inequality. That's basically it.
What are some differences between equations and inequalities?
The main difference is that when solving inequalities, if you multiply or divide by a negative number you have to be careful, since you then also have to switch the sign (for example, change a "less-than" sign to a "greater-than" sign). If you multiply or divide by an expression that contains a variable, you have to consider the two cases: that such an expression might be positive, or that it might be negative.
How do you solve inequalities using addition subtraction multiplication and division.?
In the same wasy as you solve equations except that if you multiply or divide both sides by a negative number, then the inequality changes direction.
If you divide a negative number by a negative number will you get a positive number?
You will end up with a positive number. With integers, if you multiply or divide an even amount of negative numbers, the answer will be positive and if you multiply or divide an odd amount, the answer will be negative.
What is the similarities of solving equations and inequalities?
You solve an inequality in exactly the same was as you solve an equation, by doing the same thing to both sides. The only difference is if you multiply/divide by a negative number, when you have to turn the inequality around.
When does the sign change in inequalities?
whenever you multiply or divide by a negative number

What is the easiest way you can solve inequalities?
Solve like any other math equation. One thing to remember; if you multiply or divide through by a negative number, reverse the inequality.
What happens when you multiply or divide by a negative?
the answer becomes negative

How is inequality differant from equation?
The difference is that instead of the sign "=", an inequality sign, for example "<" (less-than) is used. For solving inequalities, you can add, subtract, multiply or divide both sides by the same number, similar to an equation; however, if you multiply or divide by a negative number, the direction of the inequality changes. For example, "<" becomes ">".
Can someone tech me how to do math inequalities please answer as soon as possible.... can you show me how to figure it out?
same way you do equalities, just remember to change the greater or lesser than sign around if you multiply or divide by a negative number.

How do you use inqualities?
Inequalities are used to compare two expressions that are not equal. To solve inequalities, follow the same rules as equations (e.g. add, subtract, multiply, or divide both sides by the same number), but remember to reverse the inequality sign if you multiply or divide by a negative number. Graph the solution on a number line to represent the possible values that satisfy the inequality.
Do you switch the sign when you do inequalities?
Not always. Specifically, you switch the sign when you multiply or divide both sides of the inequality BY A NEGATIVE NUMBER. Example:4 > 3 Multiplying by -2: -8 < -6
