The absolute value of a number is always positive or zero. It is denoted by vertical bars surrounding the number, for example, the absolute value of -5 is written as |-5|, which equals 5.

What is the concept of zero?
The intuitive concept of zero is nothing or more exactly the number that measures nothing. It is the answer to a question for which one expects a numerical answer but nothing is there. For example, if someone asks how many pennies you have in your pocket and your pocket is empty, you could correctly say "zero" Mathematically, zero is the number that when added to another number does not change it. If somebody gives you zero pennies, you still have the same number you had before.
