Question

What is the absolute value of $-38$ ?

Answer 1

Hint: We know that absolute value is nothing but the positive of the given number. So, if we have a positive number, say a, then its absolute value is a itself. But when we have a negative number, say, -a, then its absolute value is a. So, using this concept, we can find the absolute value of -38.

Complete step by step solution:
We know that the absolute value is obtained when any number is transformed into a positive number.
When we take the absolute value for any function, it means that we are transforming it to a non-negative integer or taking modulus of the function.
For a number $'a'$ we can write the absolute value which is given as $\left| \pm a \right|$.
It does not depend whether the value of the given number is positive or negative it is transformed into a positive number.
We have been given numbers $-38$.
We have to find the absolute value of $-38$.
We have to take the modulus of the function as the number is to be transformed to a positive number.
Thus, we can write the absolute value as $\left| -38 \right|$
The modulus transforms any positive or negative number into positive number i.e. $\left| -38 \right|$ gives the absolute value as $38$.

Note: The absolute value is given by transforming the number into non-negative number and is given as $\left| \pm a \right|$. The modulus function is responsible for getting a non-negative number. We can find this in many formulas where a positive result is expected as an end result.
