The expression
Explanation of Solution
Given information:
The number
Formula used:
The absolute value of a number n is the denoted as
The opposite of a number n on a real number line is the exact opposite of that number with a negative sign in front of it that is
Calculation:
Consider the number
Recall that the absolute value of a number n is the denoted as
Also the opposite of a number n on a real number line is the exact opposite of that number with a negative sign in front of it that is
Therefore, the number is read as opposite of absolute value of
The modulus sign always open with a negative sign. The product of two negative signs is replaced by a positive sign.
Therefore, simplified form of
Thus, the expression
