B

Base

:
eg. 2 to the fifth = 2 times 2 times 2 times 2 times 2

The above example is a multiplication problem where 2 is multiplied by itself 5 times. Just like repeated addition becomes multiplication, there is a mathematical operation, called exponentiation, that represents repeated multiplication. We can write the expression above as

The number 2 is called the base.

Keyword(s):

D

Distance = rate * time formula

:
The distance = rate * time (d=rt) equation relates distance, rate and time.
Keyword(s):

E

Equation

:
An Equation is a mathematical sentence with an equals sign to indicate that two expressions are equal.

Exponent

:
eg. 2 to the fifth = 2 times 2 times 2 times 2 times 2

The above example is a multiplication problem where 2 is multiplied by itself 5 times. Just like repeated addition becomes multiplication, there is a mathematical operation, called exponentiation, that represents repeated multiplication. We can write the expression above as

The number 5 which represents the number of times the base is multiplied by itself is called the exponent.


Keyword(s):

Expression

:

Aa mathematical statement that may use numbers, variables, or both.

L

Linear Eqauation

:
A Linear Equation in 2 variables, is any equation that can be written in the form y = mx + b. m is called the slope and b is the y-intercept.
Keyword(s):

S

Slope of a Linear Equation

:
Slope of a Linear Equation is defined as the rise of the line over the run of the line. Given any two points on the line the slope can be calcluated by
