Algebra :
the branch of mathematics that deals with general statements of relations, utilizing letters and other symbols to represent specific sets of numbers, values, vectors, etc., in the description of such relations.

Algebra is about BALANCE
STEPS FOR SUCCESS
 Isolate the variable
Key Words
Variable : a letter or symbol that represents a number.
In the equation : n + 3 = 10
n = varaible
Expression : n + 3 is an expression because there no = sign. This means n + 3 is a PATTERN with many answers.
Equation: n + 3 = 10 is an equation because "n" can be only 1 thing. The = sign, makes n + 3 = 10 and equation.
Recursive Patterns
a pattern that goes down the table is either x or y
Funtional Pattern
 you say, I say pattern
 what do you do to x to get y
 creates an algebraic expression
Words that mean +x/
Plugin error: That plugin is not available.
Using Subtraction & Addition
9 = n+ 3
You can move an answer and = sign to the right of the equation.
5 = 3+2
3+2=5
9 = n+3 is the same as n+3 =9
2n=6
dividing does not exist.
2n=6
2n/2=6/2

Surface Area :
The surface area of a space figure is the total area of all the faces of the figure.
Prism :
A prism is a space figure with two congruent, parallel bases that are polygons.
Area :
The area of a figure measures the size of the region enclosed by the figure.
Perimeter :
The perimeter of a polygon is the sum of the lengths of all its sides.
Area of a Rectangle :
The area of a rectangle is the product of its width and length.
L x W =
Length = base of a rectangle
Width = weight of a rectangle
length and width make a right angle.
L x W =
5cm x 3cm = 15cm2
Volume:
Rectangular Prism
 area of the base x height
(LxW)H
LxWxH
20cmx5cmx10cm = 1000cm3
Area of a Triangle :
Conside a triangle with base length b and a height h. The area of the triangle is 1/2 x b x h.
Volume:
Triangular Prism
 area of the base x height
Area of a Circle :
The area of a circle is Pi x r2 or Pi x r x r, where r is the length of its radius.
Circumference of a Circle :
The distance around a circle. It is equal to Pi () times the diameter of the circle. Pi or is a number that is approximately 3.14159.
Area of a Circle :
If "L" is the sidelength of a square, the area of the square is 12 or 1 x 1.
Volume:
Cylinder
 area of te base x height
Volume:
Cube
 area of the base x height
(LxW)H
LxWxH
10cm x 10cm x 10cm = 1000cm3
