Classifying a Real Number
The numbers we use for counting, or enumerating items, are the natural numbers: 1, 2, 3, 4, 5 and so on. We describe them in set notation as { 1, 2, 3,... } where the ellipsis ( ⋯) indicates that the numbers continue to follow the pattern. The natural numbers are, of course, also called the counting numbers.
Irrational Numbers
At some point in the ancient past, someone discovered that not all numbers are rational numbers. A builder, for instance, may have found that the diagonal of a square with unit sides was not 2 or even 32 ,but was something else.
Real Numbers
Given any number n, we know that n is either rational or irrational. It cannot be both. The sets of rational and irrational numbers together make up the set of real numbers. As we saw with integers, the real numbers can be divided into three subsets: negative real numbers, zero, and positive real numbers.
Sets of Numbers as Subsets
Beginning with the natural numbers, we have expanded each set to form a larger set, meaning that there is a subset relationship between the sets of numbers we have encountered so far. These relationships become more obvious when seen as a diagram, such as Figure ( 1.1. 2 ).
Performing Calculations Using the Order of Operations
When we multiply a number by itself, we square it or raise it to a power of 2. For example, 4 2 = 4 × 4 = 16. We can raise any number to any power. In general, the exponential notation an means that the number or variable a is used as a factor n times.

Sequences are sets of numbers where each number is found by performing arithmetic operations involving the term or terms preceding it. Two common sequences are arithmetic and geometric sequences.
Why is the sequence 108 geometric?
The sequence {4,12,36,108,…} is a geometric sequence because each term is equal to the term before it multiplied by 3. Sequences are not limited to arithmetic and geometric. Each term can have any relation to the term before it, be it addition, subtraction, multiplication or division.
What is a consecutive integer?
Consecutive Integers are integers in sequence, without skipping any integers. An example of this is the series {9,10,11,12,13,14}. A consecutive integer series may also include zero, for example the series {-2,-1,0,1,2,3).
What is an odd number?
Odd Integers are all of the integers in the set of n=2k+1, where k is any integer. In simpler terms, it is every other number starting with 1. So, {1,3,5,7,9,11,13,…}. The negatives of any of these numbers is also odd, so another example of a set of odd numbers is {…,-3,-1,1,3,5,…}.
What is rational number?
Rational Numbers. Rational Numbers are numbers that can be expressed by a fraction of integers. For example 0.25 is rational because it can be expressed as 1/4. In decimal form, rational numbers will either terminate after a finite amount of digits or begin to repeat the same sequence of digits.
What is a percent increase?
Percent increase means the percent of the original that a value increases. Percent decrease means the percent of the original that a value decreases. The definition is:#N#% increase= increase/original#N#% decrease= decrease/original#N#Example: A dress on sale is marked down from $20 to $14. What percent discount (decrease) has been applied to the price of the dress?#N#The difference (decrease) is equal to $6. Dividing that by the original price ($20) gives you the equation ($6/$20) which can be simplified to (3/10) or (30/100). Stated as a percentage, the discount (decrease) is equal to 30%.
