Discrete data - ANSWERHas distinct values, can be counted, had unconnected
points (think dots)
Continuous data - ANSWERHas values within a range, measured not counted, does
not have gaps between data points (data is connected lines or curves).
Example of discrete data - ANSWERDays of the week
Expressions - ANSWERA group of symbols such as numbers and operators that has
mathematical validity
Commutative - ANSWERThe order in which the numbers appear in the sum can be
reversed
Identity property - ANSWERAdding 0 to any number does not change the original
number
Additive inverse - ANSWERValues that are equally far from 0 on the number line.
Negative - ANSWERWhen multiplying a positive number by a negative number the
result is always
Positive - ANSWERMultiplying a negative number by a negative number results in a
positive
Factors - ANSWERIntegers that evenly divide the initial integer
Prime number - ANSWERPositive integer with exactly two positive factors consisting
of 1 and itself
Composite number - ANSWERHas at least one positive factor other than one and
itself
Factorization - ANSWERProcess of breaking up a composite number into its prime
factors
fundamental theorem of arithmetic - ANSWERAny integer greater than one is either
Prime or the product of Prime numbers
Principal square root - ANSWERPositive square root of a number
Radican - ANSWERNumber under radical sign √16=4
, Open Circle - ANSWERRepresents less than or greatest than on the number line
Perfect square - ANSWERProduct of any integer with itself yields a perfect square.
Whole numbers - ANSWERpositive numbers with a whole value
Integers - ANSWERNumbers with no fractions or decimal value but can be positive
or negative
Rational numbers - ANSWERNumbers 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 - ANSWEREverything that can be included in a number line including
pi.
Fractions - ANSWERExpress numbers which are part of a whole
Numerator - ANSWERNumber written before the slash or above the fraction bar
Proper fraction - ANSWERNumerator is less than denominator and the value of the
fraction is less than one
Improper fraction - ANSWERNumerator is greater than denominator and therefore is
greater than one except with negative fractions
Mixed numbers - ANSWERA whole number and proper fraction. A negative sign in
front applies to both parts of the mixed number.
Multiples - ANSWERIntegers created by multiplying one number times another
number
Fractions - ANSWERExpress numbers which are part of a whole
Numerator - ANSWERNumber written before the slash or above the fraction bar
Proper fraction - ANSWERNumerator is less than denominator and the value of the
fraction is less than one
Improper fraction - ANSWERNumerator is greater than denominator and therefore is
greater than one except with negative fractions
Mixed numbers - ANSWERA whole number and proper fraction. A negative sign in
front applies to both parts of the mixed number.
Multiples - ANSWERIntegers created by multiplying one number times another
number
Reciprocal - ANSWERThe number which of multiplied by divisor gives you one (like
the fraction flipped over)
