Distributive Property
Multiplication outside parentheses distributing over either addition or subtraction inside parentheses does not affect the answer.
Associative Property
The grouping, without changing the order, does not affect the answer. 8+(4+2)=(8+4)+2 or 8×(2x5)=(8x2)x5
Mean
The mean of a set of data is the sum of the data values divided by the number of data values. Average
Median
The median of a set of data is the value in the middle so that there are an equal number of data values to either side of it.
Mode
The mode of a set of data is the value repeated most often.
Commutative Property
The order in which addition or multiplication is done does not affect the answer. 2+3=3+2 or 2×3=3×2
Probability
The probability of an event is the comparison of the total number of favorable outcomes to the total number of possible outcomes.
