Additive Inverse Property The sum of a number and its additive inverse always equals zero.
If I add opposites I will always get zero.
the additive inverse property states that the sum of a number and its additive inverse always equal zero.
100 x 0 =0 2x0=0
Anything multiplied by zero equals zero
The multiplicative property of zero states that the product of any real number and zero is zero Also called the zero property
Multiplicative Identity Property If you take 3 times it by 1 it equals 3
Any number times 1 equals itâ€™s self
The multiplicative identity property states that the product states that the product of any real number and one is equal to the given real number

The distributive property is taking a hard multiplication problem and making it simpler.
(2+3) x2 +
Ex. 3(78) 3(70 + 8) 3x70 + 3x8 210 + 24= 234
Any number plus 0 equals itself.
Additive identity property states that the sum of any real number and zero is equal to the given real number.
+0= Page 6
Ex. 999+0=999 2+0=2
The multiplicative inverse property states that the product of a number and its multiplicative inverse (or reciprocal) always equals one.
a/b x b/a =1 8x 1/8=1

The commutative property of addition states that the order of a problem doesn't matter Ex. 5+4=4+5 they both equal 9
The commutative property of multiplication states that it doesn't matter what order the factors are in you will still get the same product
A x B =B x A 5 billion x 3 = 3 x 5 billion

The associative property of addition states that regrouping the addens does not change the sum.
+ Page 10
Regrouping the addens does not affect the sum.
The Associative property of multiplication states that regrouping the factors does not change the product

(5 x 5) x 2 = 5 x (5 x 2)
