QUESTIONS WITH COMPLETE
SOLUTIONS
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.
