Properties of Basic Mathematical Operations Some mathematical operations have properties that can make them easier to work with and can  actually save you time. Some properties (axioms) of addition You should know the definition of each of the following properties of addition and how each can be  used. Closure  is when all answers fall into the original set. If you add two even numbers,  the answer is still an even number (2 + 4 = 6); therefore, the set of even numbers

Unformatted text preview: is closed under addition (has closure). If you add two odd numbers, the answer is not an odd number (3 + 5 = 8); therefore, the set of odd numbers is not closed under addition (no closure). • Commutative means that the order does not make any difference in the result. Note: Commutative does not hold for subtraction....

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
