Introducing intervals, which are bounded sets of numbers and are very useful when describing domain and range. We can use interval notation to show that a value falls between two endpoints. For example, -3≤x≤2, [-3,2], and {x∈ℝ|-3≤x≤2} all mean that x is between -3 and 2 and could be either endpoint.A number is obtained by dividing two integers (an integer is a number with no fractional part). “Ratio” is the root of the word. In arithmetics, a rational number is a number that can be expressed as the quotient p/q of two numbers with q ≠ 0. The set of rational numbers also includes all integers, which can be expressed as a quotient ...For example, one third in decimal form is 0.33333333333333 (the threes go on forever). However, one third can be express as 1 divided by 3, and since 1 and 3 are both integers, one third is a rational number. Likewise, any integer can be expressed as the ratio of two integers, thus all integers are rational. In other words, ⋆ ⋆ is a rule for any two elements in the set S S.
