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