Identify Property: Identify the property of addition shown by the equation a=0+a.The equation suggests that adding zero to any number gives the number itself.This is a fundamental property of addition.
Match with Choices: Match the property identified in Step 1 with the given choices.The property that adding zero to any number leaves it unchanged is known as the identity property of addition.
Confirm Other Properties: Confirm that none of the other properties fit the equation a=0+a.The associative property involves three or more numbers and their grouping, which is not applicable here.The commutative property involves the order of the numbers being added, which is also not applicable here since there is only one variable and zero.Therefore, the identity property is the correct choice.
