Notations and SymbolsIdentity Property

Additive Identity

- states that the sum is the

of any number and 0 is the

given number. Zero,”0” is the

additive identity.

Multiplicative Identity

- states that the product of

any number and 1 is the given

number. One, “1” is the

multiplicative identity.

Example 2:

Inverse Property

In Addition

- states that the sum of any number additive inverse and its additive inverse, is zero. The additive inverse of the number a is –a.

In Multiplication

- states that the product of any number and its multiplicative inverse or reciprocal, is 1. The multiplicative inverse of the

number a is 1

𝑎.

The Additive Inverse is the negation

of the element.

The Multiplicative Inverse is one

divided by the element.
