A number that indicates how many times a base number is multiplied by itself (e.g., 2³ = 2×2×2 = 8).
An exponent (or power) tells you how many times to use a number in multiplication. In the expression a^n, "a" is the base and "n" is the exponent.
a^(1/2) = √a (square root). a^(1/3) = ∛a (cube root). a^(m/n) = ⁿ√(a^m).
A number expressed as a fraction of 100, used to describe proportions and rates of change.
A measure of the spread or dispersion of a data set from its mean (average).
Three measures of central tendency used to describe the center of a data set.
A fundamental relation in geometry: the square of the hypotenuse equals the sum of squares of the other two sides.
Area measures the surface inside a shape (in square units); perimeter measures the distance around it.
A number representing a part of a whole, written as a numerator over a denominator.
