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