Discrete data
✓ Has distinct values, can be counted, had unconnected points (think
dots)
Continuous data
✓ 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
✓ Days of the week
Expressions
✓ A group of symbols such as numbers and operators that has
mathematical validity
Commutative
, ✓ The order in which the numbers appear in the sum can be reversed
Identity property
✓ Adding 0 to any number does not change the original number
Additive inverse
✓ Values that are equally far from 0 on the number line.
Negative
✓ When multiplying a positive number by a negative number the result is
always
Positive
✓ Multiplying a negative number by a negative number results in a
positive
Factors
✓ Integers that evenly divide the initial integer
Prime number
, ✓ Positive integer with exactly two positive factors consisting of 1 and
itself
Composite number
✓ Has at least one positive factor other than one and itself
Factorization
✓ Process of breaking up a composite number into its prime factors
fundamental theorem of arithmetic
✓ Any integer greater than one is either Prime or the product of Prime
numbers
Principal square root
✓ Positive square root of a number
Radican
✓ Number under radical sign √16=4
