Descriptive statistics
The gathering and processing of numerical information

Difference of two vectors
<u1, u2>  <v1, v2> = <u1  v1, u2  v2> or <u1, u2, u3>  <v1, v2, v3> = <u1  v1, u2  v2, u3  v3>

Dot product
The number found when the corresponding components of two vectors are multiplied and then summed

Expanded form
The right side of u(v + w) = uv + uw.

Exponential form
An equation written with exponents instead of logarithms.

Graph of an equation in x and y
The set of all points in the coordinate plane corresponding to the pairs x, y that are solutions of the equation.

Independent events
