FINAL EXAM REVIEW QUESTIONS AND
CORRECT ANSWERS
◉ 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.
