ACTUAL QUESTIONS AND CORRECT ANSWERS
ALREADY GRADED A+ GUARANTEED SUCCESS
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.
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.
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.
, 2
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.
composite number
, 3
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.
conditional proportion
A proportion where one part of a proportion is a variable, or unknown quantity.
numerator
The number that is written before the slash, or above the fraction bar, in a fraction.
proper fraction
A fraction where the number in the numerator is less than the number in the
denominator.
trailing zeros
Sequence of zeros after the last non-zero digit in a decimal number.
proportion
A true statement in which two ratios are equal to each other.
butterfly method
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.
unit conversion
A method used to change between measurement systems.
