This order of operation has at least four different ways it can be represented in a problem. What are the symbols that you would use to find the product of a problem?
x
.
4(5)
4 * 5
What is the difference between a power and a exponent?
Power- indicates you solve by repeated multiplication
Exponent- indicates the small number to the right & above the large number
What is an example of a binomial?

Word problems may include up to three terms to solve, true or false?
True
What does it mean to reduce the fraction to the lowest common factor?
25%= 25/100=1/4
What button on your calculator would you use to the percent sign?
For example, $20 times 15% =

What are the names of the place values to the right 7 to the left of the decimal?
See board
What is the different between "like terms" and "unlike terms"
Like terms- have variables that are the same or have terms with variables raised to the same power.
Unlike terms- have different variables or the same variable raised to different powers.
What are the typical letters used when solving for an unknown number?
What is the specific name of the unknown number?
x & y
variables
When changing a percent to a fraction, what would you write as the denominator?

dividend- 32
divisor- 8
quotient- 4
When multiplying an odd number of negatives, it will give you a positive or negative result?
Negative
What are four parts of a polynomial, and what do they represent?
Coefficient- whole number (negative or positive) and/or fraction that comes before a variable eg. 4x
Variable- typically represented by x or y but is used when there is an unknown number
Exponent- a number that gives a constant or variable power (repeated multiplication); to the right and top of the constant or variable
Constant- a number on its own that will remain the same (no variables attached & can be positive or negative)
What is the five step process to solving a word problem? You can use the acronym too.
Q.I.O.S.M
If your restaurant bill was $75.24 (including tax) and you tipped the server 25% for excellent service, how much would you pay altogether?
$75.24 * 25% = $18.81
$75.24 + $18.81= $94.05
