- 6. the set of numbers that can be expressed as a fraction , where a and b are integers and b ≠ 0. The set of rational numbers is denoted by the symbol Q.
- 9. a representation of a number by using a method to write very large or very small numbers using powers of ten that is written as a decimal with exactly one nonzero digit to the left of the decimal point, multiplied by a power of ten (e.g., 2.3 × 10–2, etc.)
- 10. – a representation of a real number, not including counting (natural) numbers, which uses a decimal point to show place values that are less than one, such as tenths and hundredths (e.g., 0.023, etc.)

- 1. – the set of positive numbers that begins at one and increases by increments of one each time {1, 2, 3, ..., n}
- 2. denoted by a number or variable in the superscript place of the base, which designates how many times the base will be multiplied by itself if it is positive or by its inverse if it is negative. If the power is 1, the base will be multiplied by 1 and will not change. If the power is 0, the simplified form will equal 1.
- 3. arranging a set of numbers based on their numerical value
- 4. the set of counting (natural numbers), their opposites, and zero {–n, …, –3, –2, –1, 0, 1, 2, 3, ..., n}. The set of integers is denoted by the symbol Z.
- 5. the set of counting (natural) numbers and zero {0, 1, 2, 3, ..., n}
- 7. the value of a digit as determined by its location in a number such as ones, tens, hundreds, one thousands, ten thousands, etc.
- 8. the number in an expression or equation which is raised to a power or exponent
