Question

Find the value of  $\left|-4\right|.\left|3\right|.$

(A) -12

(B) -1

(C) 7

(D) 12

Step-by-Step Solution

Answer

The value of $\left|-4\right|.\left|3\right|$is 12.

Step 1 – Concept of modulus

The modulus function gives the absolute value of a number irrespective of the number’s sign. It always gives a non-negative value of any number or variable. It is denoted by  $\left|x\right|.$

Step 2 – Expand the modulus

$\begin{array}{c}\left|-4\right|.\left|3\right|=-(-4)\cdot 3\\ =4\cdot 3\end{array}$

Step 3 – Multiply the numbers

$\begin{array}{c}4\cdot 3=4\times 3\\ =12\end{array}$
