## Algebra: A Combined Approach (4th Edition)

a. Natural Numbers: 1, 3 b. Whole Numbers: 0, 1, 3 c. Integers: -6, 0, 1, 3 d. Rational Numbers: -6, 0, 1, $1\frac{1}{2}$, 3, 9.62 e. Irrational Numbers: $\pi$ f. Real Numbers: -6, 0, 1, $1\frac{1}{2}$, 3, $\pi$, 9.62
Set given {-6, 0, 1, $1\frac{1}{2}$, 3, $\pi$, 9.62} a. Natural Numbers {1, 2, 3, 4, 5, 6,...} b. Whole Numbers {0, 1, 2, 3, 4, 5,...} c. Integers {..., -3, -2, -1, 0, 1, 2, 3,...} d. Rational Numbers - commonly referred to as fractions. Every integer is also a rational number since each integer can be written as a quotient of integers. i.e. $5=\frac{5}{1}$ e. Irrational Numbers - can be written as a decimal number, but the irrational number will neither terminate nor repeat. i.e. $\pi$ f. Real Numbers - all numbers (rational and irrational alike) that correspond to points on a number line.
