rational number - (answer)A number that can be written as a ratio of integers, which means it can be
written as a fraction.
product - (answer)The result of multiplying values.
whole number - (answer)A number whose value is 0 or greater and can be represented without a
fractional or a decimal component.
identity property - (answer)The property that 0 can be added to any number without changing the value
of the number. Likewise, 1 can be multiplied by any number without changing the value of that number.
associative property - (answer)The property that under certain operations in a multi-step expression,
the computations 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.
perfect square - (answer)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,...
set - (answer)In mathematics: a collection of numbers.
order of operations - (answer)A set of rules that defines the order in which mathematical operations
should be performed
multiplicative inverse - (answer)The number you must multiply x by to get 1. For example, 5 and 1/5.
principal square root - (answer)The positive square root of a number.
interval - (answer)A set of numbers between two specified values.
operators - (answer)A word or symbol (such as + or -) that indicates an operation between values.
commutative - (answer)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.
radical sign - (answer)The symbol which indicates to take the square root of the number that follows.
additive inverse - (answer)Two numbers equidistant from 0 on a number line whose sum is 0. For
example, 3 and -3.
greatest common factor (GCF) - (answer)The greatest number that is both a factor of a and a factor of b.
, factor tree - (answer)A graphical method used to identify the prime factorization of an integer.
integer - (answer)A number, (positive, negative, or zero), that can be represented without a fractional or
a decimal component.
discrete - (answer)A collection of numbers whose values are distinct, separate, and unconnected.
prime factorization - (answer)Determining the set of prime numbers whose product is the original
integer.
continuous - (answer)A collection of numbers whose values are not dividable into distinct units.
expressions - (answer)A string of terms that are connected by division, addition, and subtraction
operations.
quotient - (answer)The result of a division expression.
exponents - (answer)Sometimes called a power, it is a quantity that represents repeated multiplication.
factor - (answer)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.
composite number - (answer)A number with more factors than just one and itself. Not a prime number.
Fundamental Theorem of Arithmetic - (answer)A concept which states that any integer greater than 1 is
either prime or is the product of a unique set of prime numbers.
prime number - (answer)A number with only two factors: one and itself.
percent proportion - (answer)Proportion that is equivalent to the given ratio but has a denominator of
100.
denominator - (answer)The number written after the slash, or below the fraction bar, in a fraction.
conditional proportion - (answer)A proportion where one part of a proportion is a variable, or unknown
quantity.
numerator - (answer)The number that is written before the slash, or above the fraction bar, in a fraction.
proper fraction - (answer)A fraction where the number in the numerator is less than the number in the
denominator.
trailing zeros - (answer)Sequence of zeros after the last non-zero digit in a decimal number.
proportion - (answer)A true statement in which two ratios are equal to each other.
