What is value of 0?

The value of 0 in mathematics represents no amount or quantity. It is a fundamental number that serves as a reference point on the number line, separating negative numbers from positive numbers. Zero is neither positive nor negative and is classified as an even number because it is divisible by 23.

In terms of absolute value, the absolute value of 0 is also 0, since 0 is zero units away from itself on the number line24.

Zero has several unique properties in arithmetic operations:

• Addition: Adding 0 to any number leaves the number unchanged (e.g., (a + 0 = a)).
• Subtraction: Subtracting 0 from any number leaves the number unchanged (e.g., (a - 0 = a)).
• Multiplication: Multiplying any number by 0 results in 0 (e.g., (0 \times a = 0)).
• Division: Dividing 0 by any number results in 0, but dividing any number by 0 is undefined3.
