Identify the Properties of Mathematics (Write the name of each property shown). 1 ) When three or more numbers are multiplied, the product is the same regardless of the order of the multiplicands.
For example (a x b) x c = a x (b x c)

2 ) When two numbers are multiplied together, the product is the same regardless of the order of the multiplicands.
For example a x b = b x a

3 ) When three or more numbers are added, the sum is the same regardless of the grouping of the addends.
For example (a + b) + c = a + (b + c)

4 ) When three or more numbers are added, the sum is the same regardless of the grouping of the addends.
For example (a + b) + c = a + (b + c)

5 ) Adding 0 to any number leaves it unchanged.
For example a + 0 = a.

6 ) The product of any number and one is that number.
For example a x 1 = a.

7 ) The sum of any number and zero is the original number.
For example a + 0 = a.

8 ) When two numbers are added, the sum is the same regardless of the order of the addends.
For example a + b = b + a

9 ) Adding 0 to any number leaves it unchanged.
For example a + 0 = a.

10 ) The sum of two numbers times a third number is equal to the sum of each addend times the third number.
For example a x (b + c) = a x b + a x c

1. There are 648 total combinations that can be chosen.

2. After she choses two possiblilities the total number changes to 108 total posibilities to chose from

Step-by-step explanation:

possibility: 1/2 x 1/3 x 1/2 x 1/6 x 1/9 = 648

then you remove the first two because she chose those ones

1/2 x 1/6 x 1/9 = 108 possibilities left
