100 QUESTIONS AND ANSWERS
rational number - ------CORRECT ANSWER -----A number that can be written as a ratio of integers, which
means it can be written as a fraction.
product - ------CORRECT ANSWER -----The result of multiplying values.
whole number - ------CORRECT ANSWER -----A number whose value is 0 or greater and can be
represented without a fractional or a decimal component.
identity property - ------CORRECT 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 - ------CORRECT 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 - ------CORRECT 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 - ------CORRECT ANSWER -----In mathematics: a collection of numbers.
order of operations - ------CORRECT ANSWER -----A set of rules that defines the order in which
mathematical operations should be performed
,multiplicative inverse - ------CORRECT ANSWER -----The number you must multiply x by to get 1. For
example, 5 and 1/5.
principal square root - ------CORRECT ANSWER -----The positive square root of a number.
interval - ------CORRECT ANSWER -----A set of numbers between two specified values.
operators - ------CORRECT ANSWER -----A word or symbol (such as + or -) that indicates an operation
between values.
commutative - ------CORRECT 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 - ------CORRECT ANSWER -----The symbol which indicates to take the square root of the
number that follows.
additive inverse - ------CORRECT ANSWER -----Two numbers equidistant from 0 on a number line whose
sum is 0. For example, 3 and -3.
greatest common factor (GCF) - ------CORRECT ANSWER -----The greatest number that is both a factor of
a and a factor of b.
factor tree - ------CORRECT ANSWER -----A graphical method used to identify the prime factorization of
an integer.
integer - ------CORRECT ANSWER -----A number, (positive, negative, or zero), that can be represented
without a fractional or a decimal component.
discrete - ------CORRECT ANSWER -----A collection of numbers whose values are distinct, separate, and
unconnected.
, prime factorization - ------CORRECT ANSWER -----Determining the set of prime numbers whose product is
the original integer.
continuous - ------CORRECT ANSWER -----A collection of numbers whose values are not dividable into
distinct units.
expressions - ------CORRECT ANSWER -----A string of terms that are connected by division, addition, and
subtraction operations.
quotient - ------CORRECT ANSWER -----The result of a division expression.
exponents - ------CORRECT ANSWER -----Sometimes called a power, it is a quantity that represents
repeated multiplication.
factor - ------CORRECT 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 - ------CORRECT ANSWER -----A number with more factors than just one and itself.
Not a prime number.
Fundamental Theorem of Arithmetic - ------CORRECT 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 - ------CORRECT ANSWER -----A number with only two factors: one and itself.
percent proportion - ------CORRECT ANSWER -----Proportion that is equivalent to the given ratio but has
a denominator of 100.
denominator - ------CORRECT ANSWER -----The number written after the slash, or below the fraction bar,
in a fraction.
