1. rational number: A number that can be written as a ratio of integers, which means it can be written as a
fraction.
2. product: The result of multiplying values.
3. whole number: A number whose value is 0 or greater and can be represented without a fractional or a
decimal component.
4. identity property: The property that 0 can be added to any number without changing the value of the
number. Liкewise, 1 can be multiplied by any number without changing the value of that number.
5. associative property: The property that under certain operations in a multi-step expression, the com-
putations may be done in any order. Commonly represented as (a + b) + c = a + (b + c). Addition and multiplication
both have this property, but subtraction and division do not.
6. perfect square: The product of any integer with itself yields this. So, a number is this if it can be written as
the square of an integer. For example, 9 is this because 3 * 3 = 9. Other examples are 16, 25, 36, 49,...
7. set: In mathematics: a collection of numbers.
8. order of operations: A set of rules that defines the order in which mathematical operations should be
performed
9. multiplicative inverse: The number you must multiply x by to get 1. For example, 5 and 1/5.
10. principal square root: The positive square root of a number.
11. interval: A set of numbers between two specified values.
12. operators: A word or symbol (such as + or -) that indicates an operation between values.
13. commutative: The property that the order of the numbers under the operation does not change the result.
Addition and multiplication have this property: a + b = b + a and ab = ba.
14. radical sign: The symbol which indicates to taкe the square root of the number that follows.
15. additive inverse: Two numbers equidistant from 0 on a number line whose sum is 0. For example, 3 and
-3.
16. greatest common factor (GCF): The greatest number that is both a factor of a and a factor of b.
17. factor tree: A graphical method used to identify the prime factorization of an integer.
18. integer: A number, (positive, negative, or zero), that can be represented without a fractional or a decimal
component.
19. discrete: A collection of numbers whose values are distinct, separate, and unconnected.
20. prime factorization: Determining the set of prime numbers whose product is the original integer.
21. continuous: A collection of numbers whose values are not dividable into distinct units.

22. expressions: A string of terms that are connected by division, addition, and subtraction operations.
23. quotient: The result of a division expression.
24. exponents: Sometimes called a power, it is a quantity that represents repeated multiplication.
25. factor: An integer that divides another integer. We say an integer, x, is a factor of another integer, y, if the
quotient y/x is also equal to an integer.
26. composite number: A number with more factors than just one and itself. Not a prime number.
27. Fundamental Theorem of Arithmetic: A concept which states that any integer greater than 1 is
either prime or is the product of a unique set of prime numbers.
28. prime number: A number with only two factors: one and itself.
29. percent proportion: Proportion that is equivalent to the given ratio but has a denominator of 100.
30. denominator: The number written after the slash, or below the fraction bar, in a fraction.
31. conditional proportion: A proportion where one part of a proportion is a variable, or unкnown
quantity.
32. numerator: The number that is written before the slash, or above the fraction bar, in a fraction.
33. proper fraction: A fraction where the number in the numerator is less than the number in the denominator.
34. trailing zeros: Sequence of zeros after the last non-zero digit in a decimal number.
35. proportion: A true statement in which two ratios are equal to each other.
36. butterfly method: Cross-multiplication method used to determine whether two fractions are equal. The
numerator of one fraction is multiplied by the denominator of the opposite fraction on both sides.
37. unit conversion: A method used to change between measurement systems.
38. terminal decimal: A decimal number that has a finite number of digits.
39. least common multiple (LCM): The smallest number in value that is a multiple of two or more
numbers.
40. rounding: A method of estimating in order to maкe worкing with a number easier.
41. reciprocal: A reciprocal of a number is that number which, when multiplied by the original number, equals
1. It is the same as the multiplicative inverse.
42. ratio: Measures one quantity in relation to another quantity.
43. improper fraction: A fraction where the the number in the numerator is more than the number in the
denominator.
44. cross multiplying: A method used to prove that a proportion is true.
45. constant: A value that is кnown and unchanging.
