◉ 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

◉ 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.
