Yes, when evaluating an expression inside absolute value signs, you first solve the expression as you would normally, following the order of operations from left to right. After obtaining the result, if it's negative, you convert it to its positive counterpart, since absolute values always yield non-negative results. For example, |−3| equals 3, while |4| remains 4.

Evaluate each expression | 9?
Evaluate each expression. | 9 | = -9 because Multiplying and Dividing with Positive and Negative Numbers. ... When the signs of the two numbers are the same, the answer will be positive. When the signs of the two numbers are different, the answer will be negative.
How do you simplify absolute value?
To simplify an absolute value expression, you need to determine the value of the expression inside the absolute value bars and consider whether it is positive or negative. If the expression is non-negative, the absolute value is simply the expression itself. If it is negative, the absolute value is the expression multiplied by -1. For example, |x| can be simplified to x if x ≥ 0, and to -x if x < 0.
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.
When is there no solution possible to an absolute value equation and why?
For example: | x | = -1 Or any other equation where the absolute value of any expression is negative. This doesn't have a solution, because the absolute number of any expression is always positive, or zero, never negative.
Absolute value of x plus 7?
The absolute value of any number is the "distance from zero". If the expression is negative, it is converted to positive. The absolute value of x+7 can be either x+7 (if x+7 is positive) or -(x+7) (if x+7 is negative).

Absolute value with a negative on the outside?
If you mean something like: | x | = -1 That has no solution. The absolute value of any expression on the inside of the absolute value bars can only be zero or positive.
Absolute value of x plus 7?
The absolute value of any number is the "distance from zero". If the expression is negative, it is converted to positive. The absolute value of x+7 can be either x+7 (if x+7 is positive) or -(x+7) (if x+7 is negative).
Absolute value of 1.5?
The absolute value of a positive number is the same number - in this case, 1.5. The absolute value of a negative number is the number, without the sign. Note that the absolute value of an expression like (-x) is not necessarily (x); rather, you have to separately consider the case that x is positive, or that x is negative. For example, the absolute value of x is x (if x is positive), or (-x) (if x is negative).
What is the absolute value for the positive?
the absolute value for a negative or positive value is always positive
Is it possible to have no solution when you solve an inequality?
Yes, for example: | x | < 0 (since the absolute value of any expression is always positive or zero) or: (x+5)2 < 0 (Similar to the above: since the square of any expression is also positive or zero).
Is the absolute of a positive integer is a negative integer?
No. The absolute value of a number is the value of the number ignoring the sign - it is always positive: The absolute value of a negative number is a positive number; The absolute value of a positive number is a positive number.
Why does the expression -a does not always represent a negative number?
* If "a" is positive, "-a" is negative.* If "a" is negative, "-a" is positive. * If "a" is zero, "-a" is zero. If you want to force a negative number, you can write -|a|, i.e., the negative of the absolute value.
