QUESTIONS AND ANSWERS 2025
rational number - CORRECT-ANSWERSA number that can be
written as a ratio of integers, which means it can be written
as a fraction.
product - CORRECT-ANSWERSThe result of multiplying
values.
whole number - CORRECT-ANSWERSA number whose value
is 0 or greater and can be represented without a fractional or
a decimal component.
identity property - CORRECT-ANSWERSThe 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-ANSWERSThe 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-ANSWERSThe 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-ANSWERSIn mathematics: a collection of
numbers.
order of operations - CORRECT-ANSWERSA set of rules that
defines the order in which mathematical operations should
be performed
multiplicative inverse - CORRECT-ANSWERSThe number you
must multiply x by to get 1. For example, 5 and 1/5.
principal square root - CORRECT-ANSWERSThe positive
square root of a number.
interval - CORRECT-ANSWERSA set of numbers between two
specified values.
operators - CORRECT-ANSWERSA word or symbol (such as +
or -) that indicates an operation between values.
, commutative - CORRECT-ANSWERSThe 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-ANSWERSThe symbol which indicates
to take the square root of the number that follows.
additive inverse - CORRECT-ANSWERSTwo numbers
equidistant from 0 on a number line whose sum is 0. For
example, 3 and -3.
greatest common factor (GCF) - CORRECT-ANSWERSThe
greatest number that is both a factor of a and a factor of b.
factor tree - CORRECT-ANSWERSA graphical method used to
identify the prime factorization of an integer.
integer - CORRECT-ANSWERSA number, (positive, negative,
or zero), that can be represented without a fractional or a
decimal component.
discrete - CORRECT-ANSWERSA collection of numbers whose
values are distinct, separate, and unconnected.
prime factorization - CORRECT-ANSWERSDetermining the set
of prime numbers whose product is the original integer.
