Discrete data - ANSWER: Has distinct values, can be counted, had unconnected
points (think dots)
Continuous data - ANSWER: Has values within a range, measured not counted, does
not have gaps between data points (data is connected lines or curves).
Example of discrete data - ANSWER: Days of the week
Expressions - ANSWER: A group of symbols such as numbers and operators that has
mathematical validity
Commutative - ANSWER: The order in which the numbers appear in the sum can be
reversed
Identity property - ANSWER: Adding 0 to any number does not change the original
number
Additive inverse - ANSWER: Values that are equally far from 0 on the number line.
Negative - ANSWER: When multiplying a positive number by a negative number the
result is always
Positive - ANSWER: Multiplying a negative number by a negative number results in a
positive
Factors - ANSWER: Integers that evenly divide the initial integer
Prime number - ANSWER: Positive integer with exactly two positive factors
consisting of 1 and itself
Composite number - ANSWER: Has at least one positive factor other than one and
itself
Factorization - ANSWER: Process of breaking up a composite number into its prime
factors
fundamental theorem of arithmetic - ANSWER: Any integer greater than one is either
Prime or the product of Prime numbers
Principal square root - ANSWER: Positive square root of a number
, Radican - ANSWER: Number under radical sign √16=4
Open Circle - ANSWER: Represents less than or greatest than on the number line
Perfect square - ANSWER: Product of any integer with itself yields a perfect square.
Whole numbers - ANSWER: positive numbers with a whole value
Integers - ANSWER: Numbers with no fractions or decimal value but can be positive
or negative
Rational numbers - ANSWER: Numbers that can be expressed as a fraction or
decimal values that have that end or repeat forever. Includes all integers since all
integers can be expressed as fractions.
Real numbers - ANSWER: Everything that can be included in a number line including
pi.
Fractions - ANSWER: Express numbers which are part of a whole
Numerator - ANSWER: Number written before the slash or above the fraction bar
Proper fraction - ANSWER: Numerator is less than denominator and the value of the
fraction is less than one
Improper fraction - ANSWER: Numerator is greater than denominator and therefore
is greater than one except with negative fractions
Mixed numbers - ANSWER: A whole number and proper fraction. A negative sign in
front applies to both parts of the mixed number.
Multiples - ANSWER: Integers created by multiplying one number times another
number
Fractions - ANSWER: Express numbers which are part of a whole
Numerator - ANSWER: Number written before the slash or above the fraction bar
Proper fraction - ANSWER: Numerator is less than denominator and the value of the
fraction is less than one
Improper fraction - ANSWER: Numerator is greater than denominator and therefore
is greater than one except with negative fractions
