Step-by-step solution

Step-1 – Absolute value of a number

Absolute value of any positive or negative number is always positive and equal to the magnitude of the number. The absolute value of a number N is denoted by $\left|N\right|$.

The absolute value of a number represents the distance of the number from 0 in the number line.

Step-2 – Example of Absolute value

The absolute value of 3 is denoted by $\left|3\right|$and is equal to 3.

And the absolute value of $-4$is denoted by $\left|-4\right|$and is equal to 4.

Step-3 – Evaluate the absolute value

The number $21$ is at a distance of 21 units to the right of 0 on the number line.

So, the absolute value of the given number 21 is given by

$\left|21\right|=21$

Thus, the absolute value of the given number is 21.
