and Answers 2024/2025
Principal square root - correct answer "The positive square
root of a number. For example, the principal square root of 36 is
6."
Whole number - correct answer A number whose value is 0 or
greater (negative numbers are not considered this), and can be
represented without a fractional or a decimal component.
Positive number - correct answer "A number whose value is
greater than zero. On the number line, these numbers are to the
right of zero."
Additive inverse - correct answer "Two numbers equidistant
from 0 on a number line whose sum is 0. For example, 3 and -3
Commutative - correct answer The property that the order of
the numbers under the operation does not change the result.
Addition and multiplication are this: a + b = b + a and ab = ba.
Multiplicative inverse - correct answer "opposite of a number
x is the number you must multiply x by to get 1. For example, 5
and 1/5 are this."
,Negative square root - correct answer "The negative
compliment of a perfect square. For example, -6 is the this of 36."
Operation - correct answer "In mathematics, this is a
procedure which generates a new value from one or more
operands, or mathematical values."
P(not A) = ? - correct answer 1 - P(A)
For Disjoint Events: P(A or B) = ? - correct answer P(A) +
P(B)
For Non Disjoint Events: P(A or B) = ? - correct answer P(A)
+ P(B) - P(A and B)
For Independent Events: P(A and B) = ? - correct answer P(A)
* P(B)
For Dependent Events: P(A and B) = ? - correct answer P(A) *
P(B | A)
For Disjoint Events: P(A and B) = ? - correct answer 0
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."
,Rational number - correct answer "This type of number is a
number that can be written as a ratio of integers, which means it
can be written as a fraction."
Order of operations - correct answer A set of rules that
defines the order in which mathematical operations should be
performed
Associative property - correct answer "This property holds
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 follow
this property"
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.
Composite number - correct answer A number with more
factors than just one and itself.
Multiplication - correct answer "In mathematics, this is the
act of adding the same number multiple times. It is often denoted
by the dot sign, ·."
, Base number - correct answer "The number multiplied by
itself when paired with an exponent. For example, in 8 to the
third power, 8 would be this number."
Radicand - correct answer The number within the radical
sign whose square root is to be taken.
Factor tree - correct answer A graphical method used to
identify the prime factorization of an integer.
Subtraction - correct answer Taking one or more values away
from another.
Set - correct answer In mathematics: a collection of numbers.
Factor - correct answer "An integer that divides another
integer. We say an integer, x, is a this of another integer, y, if the
quotient y/x is also equal to an integer."
Quotient - correct answer The result of a division expression.
Greatest common factor (GCF) - correct answer This is, of
any two integers a and b, the greatest number that is both a
factor of a and a factor of b.
Cross products - correct answer The results produced from
cross multiplication.
