Using Absolute Values in Equations and Inequalities Lesson Summary Frequently Asked Questions What is the absolute value of |- 3? We want to find |-3|. If we plot -3 on a number line and count the units from 0, we'll see it's 3 units to the left of 0. 3 is the positive vers...
A common task in math is to compute what is called the absolute value of a given number. We typically use vertical bars around the number to notate this, as can be seen in the picture. We would read the left side of the equation as "the absolute value of -4." Computers and calculat...
values above or below the mean value, profit, or loss in a transaction. The sign of the numeric value is ignored in absolute value, and only the numeric value is examined.
Commenting, after the lecture, about the slide with the analytic solution of example 2, he said, after complaining that the lecture was going too fast for him: “According to me, I usually put values, like… 2, 1…, to digest and then I come here, I say, less than 0, it will ha...
In this last video, we show more examples of absolute value equations that have no solutions.Solve inequalities containing absolute valuesLet’s apply what you know about solving equations that contain absolute values and what you know about inequalities to solve inequalities that contain abso...
When typingmath as text, such as in an e-mail, the "pipe" character is usually used to indicate absolute values. The "pipe" is probably a shift-key somewhere north of the "Enter" key on your keyboard. While the "pipe" denoted on the physical keyboard key may look like a "broken" ...
In the last section, we saw examples of solving equations with absolute values where the only operation was addition or subtraction. Now we will see how to solve equations with absolute value that include multiplication.Remember that absolute value refers to the distance from zero. You can ...
Absolute values are also used in calculating themean deviation. Adeviationin statistics is the difference between a data point and the mean. The absolute value of the deviation removes any minus signs that occur. If we didn’t use the absolute value, the pluses and minuses would cancel each...
For that inequaltiy to be true, what values could a have?Geometrically, a is less than 3 units from 0. Therefore,−3 < a < 3.This is the solution. The inequality will be true if a has any value between −3 and 3.In general, if an inequality looks like this --|a| < b....
