What is the symbol of absolute value?
Just a pair of straight vertical lines, one on either side of the number. The absolute value of 18k is |18k| . The absolute value of 'x' is |x| .
How do you solve absolute-value equations and inequalites?
Absolute Value means the distance from 0, and so you should solve the equation with the number inside the Absolute Value lines as a positive and then solve again as a negative.
What is the thing in trig called that has a letter in the center and double vertical lines on both sides?
Double verticle lines surrounding an expression means to take the absolute value of the expression. The absolute value of an expression is the expression if it is positive, and the negative of the expression if it is negative, i.e. the unsigned distance from zero. Analytically, in order to process the expression, the absolute value of an expression is also the square root of the square of the expression.
The distance from cero of the number line?
That is called the "absolute value" of a number.
How do you find absolute value of positive and negative numbers?
To find the absolute value of a positive number all the answer is is the number in between the lines. For example, the absolute value of [340] is 340. To find the absolute value of a negative number, it is simply the opposite (positive version) of the negative number. For example, the absolute value of [-56] is just 56.
