I just thought of one; although there may be a better way to do this than Absolute Value. Suppose you were using a Spreadsheet like Excel to create a rough draft of your operating budget for the next year. You have four employees, one took a one year unpaid sabbatical. So you would have Column A with the name of your employees and Column B with their salaries this year. It would look something like this:

Kim Forbes$60,000.00Darryl Star$120,000.00Micheal Burros$34,000.00Aislynn Rodrigues-$52,000.00

If you did a normal Excel calculation you would get:

=SUM(B2:B5)

or

$162,000

That would really not help you with next years budgeting because you expect Aislynn to come back January 1st at her previous salary. That sum only shows you the operating budget, minus Aislynn's salary.

If you used Absolute Value, you would get:

=SUM(B2:B4,ABS(B5))

or

$266,000

That would be a true estimation of your salary costs next year.

The absolute value of 200 is 200, and so is the absolute value of -200 .

Absolute value is a number's distance from zero on the number line.

First, subtract the absolute values of the integers, then use the greater absolute value's sign.

You use place value for all decimal numbers that contain fractional parts. You also use place value for all decimal integers other than those containing only one-digit.

Absolute value is a number's distance from zero on the number line.

ABS returns the absolute value, so you use it any time you want to view or calculate with the absolute value.

An absolute value may not need a number line to solve. Absolute value means the distance form zero regardless of the sign.

This is used mainly be engineers. However, many people use it intuitively in real-life (non-engineering) situations, for example: to find the distance between two points on a road, with road distance markers "5 km." and "7 km.", you can subtract any of the numbers from the other, and get either 2 or -2. Since you are not interested in the direction, only in the distance, you then take the absolute value. Alternately, you can arrange the numbers so that you subtract the smaller number from the larger number from the start.

Hi, my daughter's math teacher recommended a website to his students. It has a lot of math video lessons on various math topics, including the one you need help with. Please click the below link 'Free absolute value inequalities video'. It is all FREE to use! It was very helpful for my child. Hope it will help you, too. Good luck!

You can write this as a complex number; the resistance is the real part, the reactance is the imaginary part (negative, for a capacitive reactance): 15 + j10 kilohms. ("j" is used instead of "i", to avoid confusion with current, which is symbolized by "i".) This is in rectangular coordinates; with a scientific calculator you can use rectangular --> polar conversion, to get the absolute value and the angle. To get just the absolute value, use Pythagoras' Theorem, which in this case gives about 18 kilohms.You can write this as a complex number; the resistance is the real part, the reactance is the imaginary part (negative, for a capacitive reactance): 15 + j10 kilohms.

No. The sign you will use is going to be the sign with the greater absolute value.
