Notebook Examples:Properties: (In the Resource
Section)Commutative Property of Additiona + b = b + a 2 + 3 = 3 +
2
Commutative Property of Multiplicationa b = b a 2 ( 3 ) = 3 ( 2
)
The Commutative Property says that the order of the numbers
being added or multiplied does not matterFormulas: (Resource)1.
Perimeter of a rectangle:P = 2L + 2W2. Area of a rectangle:A = L x

1. Expression:A mathematical sentence which does not contain an
equal sign. 3x + 8 + 4x y is an expression. 2. Equation:Equations
are sentences which do have an equal sign. 3(x + 8) + 4x = 32 is an
equation. With equations, you do solve for any variables. When you
see an =, you are to find the value of the variable. Always solve
for the positive value of the variable.In an expression, you do not
solve for any variables. Expressions are simplified by combining
like terms.Vocabulary: (Resource)Notebook Examples:
Vocabulary: (Resource)3. Constant:A Constant is a number that
does not change.4. Variable:A variable is a number that we dont
know yet. Once the variable is solved for, it becomes a
constant.State the constant and the variable, then write the
equation describing the following:You make $5.00 an hour and want
to know how many hours you need to work to make $125.00

three times a number x.
Translating Expressions
After Translating, Equations are solved for the unknown
variable1. Five less than a number is 18. What is the
number?2.Two-thirds of a number is equal to 11. What is the number?
3. A board 76 inches long is cut into two pieces. One piece is 5
inches less than twice as long as the first. How long is each
piece?
