\ A number that can be written as a ratio of integers, which means it can be written as a
fraction. - ANS✔✔-rational number
The result of multiplying values. - ANS✔✔-product
A number whose value is 0 or greater and can be represented without a fractional or a
decimal component. - ANS✔✔-whole number
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. - ANS✔✔-identity 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. -
ANS✔✔-associative property
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,... - ANS✔✔-perfect square
In mathematics: a collection of numbers. - ANS✔✔-set
A set of rules that defines the order in which mathematical operations should be
performed - ANS✔✔-order of operations
The number you must multiply x by to get 1. For example, 5 and 1/5. - ANS✔✔-
multiplicative inverse
The positive square root of a number. - ANS✔✔-principal square root
A set of numbers between two specified values. - ANS✔✔-interval
A word or symbol (such as + or -) that indicates an operation between values. -
ANS✔✔-operators
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. -
ANS✔✔-commutative
The symbol which indicates to take the square root of the number that follows. -
ANS✔✔-radical sign
Two numbers equidistant from 0 on a number line whose sum is 0. For example, 3 and -
3. - ANS✔✔-additive inverse
The greatest number that is both a factor of a and a factor of b. - ANS✔✔-greatest
common factor (GCF)
A graphical method used to identify the prime factorization of an integer. - ANS✔✔-
factor tree

Answers
A number, (positive, negative, or zero), that can be represented without a fractional or a
decimal component. - ANS✔✔-integer
A collection of numbers whose values are distinct, separate, and unconnected. -
ANS✔✔-discrete
Determining the set of prime numbers whose product is the original integer. - ANS✔✔-
prime factorization
A collection of numbers whose values are not dividable into distinct units. - ANS✔✔-
continuous
A string of terms that are connected by division, addition, and subtraction operations. -
ANS✔✔-expressions
The result of a division expression. - ANS✔✔-quotient
Sometimes called a power, it is a quantity that represents repeated multiplication. -
ANS✔✔-exponents
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. - ANS✔✔-factor
A number with more factors than just one and itself. Not a prime number. - ANS✔✔-
composite number
A concept which states that any integer greater than 1 is either prime or is the product
of a unique set of prime numbers. - ANS✔✔-Fundamental Theorem of Arithmetic
A number with only two factors: one and itself. - ANS✔✔-prime number
Proportion that is equivalent to the given ratio but has a denominator of 100. - ANS✔✔-
percent proportion
The number written after the slash, or below the fraction bar, in a fraction. - ANS✔✔-
denominator
A proportion where one part of a proportion is a variable, or unknown quantity. -
ANS✔✔-conditional proportion
The number that is written before the slash, or above the fraction bar, in a fraction. -
ANS✔✔-numerator
A fraction where the number in the numerator is less than the number in the
denominator. - ANS✔✔-proper fraction
Sequence of zeros after the last non-zero digit in a decimal number. - ANS✔✔-trailing
zeros
A true statement in which two ratios are equal to each other. - ANS✔✔-proportion
Cross-multiplication method used to determine whether two fractions are equal. The
numerator of one fraction is multiplied by the denominator of the opposite fraction on
both sides. - ANS✔✔-butterfly method
