Identity Property

The identity property is a fundamental property in mathematics that applies to both addition and multiplication. It states that when you add or multiply a number by its identity element, the result is the original number itself. The identity element for addition is 0, and for multiplication, it is 1.

Identity Property of Addition

When you add any number to 0, the result is the original number. This can be expressed as:

a + 0 = a

For example, 5 + 0 = 5

Identity Property of Multiplication

When you multiply any number by 1, the result is the original number. This can be expressed as:

a * 1 = a

For example, 7 * 1 = 7
