Properties of Whole Numbers - Identity of Addition and Multiplication of Whole Numbers

notes

Identity means that whatever the number or value may be, the answer stays the same in mathematical operations like addition and multiplication.

• Additive identity means that we get the same whole number when added to another whole number.
• Zero is called an identity for the addition of whole numbers or additive identity for whole numbers i.e., a + 0 = a, (a is any whole number).
• Example, 0 + 15 = 15

2. Multiplicative Identity:

• Multiplicative identity means that we get the same whole number when multiplied by another whole number.
• Zero has a special role in multiplication too. Any number, when multiplied by zero, becomes zero. Example, 5 × 0 = 0
• 1 is the identity for multiplication of whole numbers or multiplicative identity for whole numbers.
• Example, 1 × 100 = 100.
