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
1
, 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
