First let us know what absolute value is and then will know the absolute value of zero.
The value which refers to the distance of a number from the origin of a number line is called absolute values. It is represented as |a|, which defines the magnitude of any integer ‘a’. The absolute value of any integer, whether positive or negative, will be the real numbers, regardless of which sign it has. It is represented by two vertical lines |a|, which are known as the modulus of a.
Absolute value of zero
Zero is neither positive nor negative. But the absolute value of any non-zero number can be thought of as it’s distance from zero and it will always be positive.
There is no absolute value for 0 because the absolute value changes the sign of the numbers into positive and zero has no sign.
