Choose the number sentence that shows the identity property of addition. a. 122 = 61 + 61 b. 62 = 1 + 61 c. 61 = 0 + 61

For this case we have that by definition, the property: Identity element of the zero-sum establishes:

Example:

The number "0" is the only element that retains the identity in the operation of the sum.

Thus, the equation: is an example of this property.
