Algebra


Simple Interest Formula

Interest = principle × rate × time
I = prt
read as “I am pretty ”


Distance Formula

Distance = rate × time
d = rt
remember as dirt

Speed, Distance and Time

    Remember the formula triangle

    D = distance traveled
    S = Average speed
    T = Time taken

    You can use the formula triangle in the following way:
    If you need to find D, cover up D in the triangle and you get S × T

    If you need to find S, cover up S in the triangle and you get

    If you need to find T, cover up T in the triangle and you get

The following video shows how to use the average speed pyramid or triangle and the acceleration triangle.

 

 

Linear Equations (Slope-Intercept Form)
Begin, Move: the use of m and b in y = mx + b

To graph such a line equation, begin at the value of b, then move according to the value (slope) of m.

This is the video form of a mnemonic (memory) device It can help students learn the important aspects of the slope-intercept (y=mx+b) form of linear equations.

 

 

Multiplying Binomials

Multiply the terms of two binomials in this order.
For example (x- 2)(x + 1),
FOIL: First, Outside, Inside, Last.


Word-Problem Solving Strategy

S-T-A-R
Search the word problem.
Translate the words into an equation.
Answer the problem.
Review the solution.

 

 

Quadratic Formula

A song to remember the quadratic formula sung to the tune of "Pop Goes the Weasel"

x equals negative B
Plus or minus square root
of B squared minus four A C
All over two A.

Here is the quadratic formula song in video. An easy way to remember the formula.

Here is another version of the song to help you learn the quadratic formula and how to use it to solve quadratic equations.
