A letter used to represent one or more numbers.
Additive Identity Property
The sum of a number and zero is always that number. For example, a + 0 = a.
Multiplicative Identity Property

The probability that the outcome or occurrence of the first event affects the outcome or occurrence of the second event so that the probability is changed. An example.... drawing a Reese's from a candy jar filled with 10 different candy bars will effect the probability of drawing another Reese's candy bar.
A pattern in which each term is found by multiplying the previous term by the same number.
