What is the identity property of addition?

• Adding one to any number does not change the value of that number (e.g., a + 1 = a)

• Adding zero to any number does not change the value of that number (e.g., a + 0 = a)

• Subtracting zero from any number does not change the value of that number (e.g., a - 0 = a)

• Multiplying any number by one does not change the value of that number (e.g., a * 1 = a)

What is the associative property of addition?

• The associative property of addition states that the way in which numbers are grouped does not change their sum (e.g., (a + b) + c = a + (b + c)).

• The associative property of addition states that the order of numbers does not affect their sum (e.g., a + b = b + a).

• The associative property of addition states that adding zero to a number does not change its value (e.g., a + 0 = a).

• The associative property of addition states that the sum of two negative numbers is always positive.
