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(<=).

When does the sign change in inequalities?

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.


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 happens when you multiply or divide by a negative?

the answer becomes 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.


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.


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.


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.


If you add a negative and a negative what do you get?

Adding negatives? You get a negative. But if you multiply/divide 2 negatives, that's a positive.


How can you Make a negative number into a positive value?

You can multiply or divide it by any negative number.


How do you divide a negative number by a positive fraction?

You multiply the negative number by the reciprocal of the fraction.


How is inequality differant from equation?

The difference is that instead of the sign "=", an inequality sign, for example "&lt;" (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, "&lt;" becomes "&gt;".


Do you switch the sign when you multiply or divide an inequality?

Only when what you're multiplying by/dividing by is negative.


Do two negative integers equal a positive?

Only when you divide or multiply.


What is 4 times negative 2?

4 x -2= -8 if the signs are the same when you multiply or divide, it's positive. if the signs are different when you multiply or divide, it's negative.


What happers if you multiply or divide two negative numbers?

When you divide or multiply two negative numbers they cancel each other out and you have a positive answer. We are measuring relationships instead of moving on a number line like addition or subtraction.


What is the result when you pare one positive number with one negative number?

If you multiply or divide the numbers, the answer will be negative.

Explain how solving inequalities is alike and different from solving equations?

Most of the steps are the same. The main difference is that if you multiply or divide both sides of an inequality by a NEGATIVE number, you must change the direction of the inequality sign (for example, change "less than" to "greater than").


How do you solve a inequalities?

It depends on the form of the inequality, 1 or 2 variables etc. But in general, try solving it like an equality but remember to change the less than or greater than signs if you multiply or divide by a negative number. If you want to post an example question, that would be great.


If you multiply or divide both sides of an inquality by a negative number you need to?

Change the direction of the inequality.
