• rational number -✓✓ A number that can be written as a ratio of integers, which means
it can be written as a fraction.
• 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.
