Constant term and Division of fractions property
• A Constant term is the part of a equation that has no
variables.
p(x)=2x3–4x2+9x–5 (5 is the answer)
L(h)=8x12-12x6+18h-3 (3 is the answer)
• Division of fractions property is basically dividing a
fraction is the same as multiplying by it’s reciprocal.
The reciprocal of ½ is 2.
10 ÷ ½ = 10 x 2 = 20
The reciprocal of ¼ is 4.
10 ÷ ¼ = 10 x 4 = 40
Equation and Equivalent equations
• Equation is a number sentence that contains a
equal sign.
4+5=9
25+95=120
• Equivalent equations are number models that
equal the same on both sides.
A+O=O+A
3+9=9+3
Inequality and Integers
• Inequality any number sentence with ≥, ≤, >,
<, =
5>2
78<1234321
• Integers are positive and negative numbers.
-4, -5, -6, 7, 8, 9
Multiplication property of -1 and Nested parentheses
• Multiplication property of -1 you multiply any
number by -1 you will get it’s opposite.
-1x23=-23
-1x-23=23
• Nested parentheses are a set of more than
one set of parentheses in side another.
(2+(3x8))x5-10=x
7x6x((8+10)-4)+7
Open sentence and Opposite of a
number
• Open sentence is a number sentence that is
neither true or false because one or more
variables are in it.
Yx4-6+G=A
7-8+21-t+a=S
• Opposite of a number: the opposite number is if
the negative is positive and the positive is
negative.
-6=6
-123456789=123456789
Order of operations and Reciprocal and Relation
symbol
• Order of operations rules to tell in what order to preform
operations in.
Parentheses
Exponents
Multiplication
Division
Addition
Subtraction
• Reciprocal is the opposite of the fraction.
½ is the reciprocal of 2/1 12321/6 is the reciprocal of 6/12321
• Relation symbol a symbol used to express a relationship with
answers between two quantities.
76<84
49>42
Repeating decimals and Solution
• Repeating decimals is a decimal number that
has digits that repeat forever.
3.5556555655565556…
5.888
• Solution comes after the equal sign and the
answer to the problem.
4x5=20
9+5=14
Solution set and Terminating decimals
• Solution set is a set of all solutions of an
equation or inequality.
X = 36 x =6x6
R =64 R =8x8
• Terminating decimals is a decimal number
that has digits that doesn't go on forever.
0.4
0.25
Trial and error method and Variable
• Trial and error method is where you guess for
a equation and make sure the answer is right
5 25 6x5=30 5x5=25
• Variables are the a symbol for a number you
don't know yet.
Yx5+4=?
15+5-10x3/y=?
