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