For every whole number a, a + 0 = 0 + a = a. 0 is called the Identity element for addition in the set of W. |
For every whole number a, a x 1 = 1 x a = a 1 is called the multiplicative identity for whole numbers. |
For every whole number a, a x 0 = 0 x a = 0 This is called the Zero Property of Multiplication for the set of W. |
For every whole number a, a ÷ 1 = a. |
