Properties of zero

The two properties of zero are the addition property of zero and the multiplication property of zero.

The figure below illustrates the addition property of zero and it can be written as 2 + 0 = 2

Addition property of zero:

The addition property of zero says that a number does not change when adding or subtracting zero from that number.

Examples showing the addition property of zero

4 + 0 = 4

12 + 0 = 12

5 − 0 = 5

48 − 0 = 48

0 + 1 = 1

a − 0 = a

x + 0 = x

0 − 12 = -12

(a + b) + 0 = a + b

0 − y = -y

Formal definition of the addition property of zero

For every number real number a, a + 0 = a and 0 + a = a

Addition property of zero

Multiplication property of zero

The multiplication property of zero says that zero times any number is equal to zero.

Examples

2 × 0 = 0

0 × 12 = 0

-5 × 0 = 0

23344555677888882 × 0 = 0

x × 0 = 0

(x + y + z + r )× 0 = 0

Formal definition of the multiplication property of zero

For every number real number a, a × 0 = a and 0 × a = 0

The different names given to the addition property of zero or the multiplication property of zero

The different names given to the addition property of zero

  • Addition property of zero
  • Identity property of zero
  • Additive property of zero
  • Zero property of addition
  • Identity property of addition
  • Additive identity property


The different names given to the multiplication property of zero

  • Multiplication property of zero
  • Multiplicative property of zero
  • Zero property of multiplication

Other properties of zero

Division by zero is undefined or has no answer. For example, 9/0 has no answer. 

The number 0 is called the additive identity.

Any number to the power of 0 is equal to 1.

0 is neither positive nor negative.

0 is neither prime nor composite.

Additive inverse property

If you add two numbers and the sum is zero, we call the two numbers additive inverses or opposites of each other.

For example, 2 is the additive inverse of -2 because 2 + -2 = 0

-2 is also the additive inverse of 2 because -2 + 2 = 0
