•
PEMDAS
- ✔✔(parenthesis, exponents, multiplication, division, addition, subtraction) work left to right
•
Exponential Notation
- ✔✔Ex: 6^4, 2^3, 9^10, etc.
•
Expanded Form
- ✔✔Ex: 7x7x7, 6x6, 2x2x2x2x2, etc.
•
Standard Notation
- ✔✔Ex: 5^2= 25; 25 is the standard notation (the answer or solution)
•
+x+
- ✔✔=+
•
+x-
- ✔✔=-
•
-x-
- ✔✔=+
•
Adding or Subtracting fractions
- ✔✔You need a common denominator
•
Multiplying fractions
- ✔✔no special rule, just multiply Ex: 2/5 x 3/9= 6/45
•
Dividing fractions
- ✔✔flip 2nd fraction and multiply Ex: 2/5 divided by 3/9= 2/5 x 9/3
•
Solving Equations w/ fractions
, - ✔✔either multiply both sides of the equation by the reciprocal of the fraction, or multiply
both sides of the equation by the denominator of the fraction
•
Percent Increase or Decrease problems
- ✔✔Formula: amount of change/ original number. Ex: Find the percent decrease if the price
changes from $60 to $39. 60-39= 21. amount of change= $21 original number= $60. $21/$60=
0.35. Convert to percents. 0.35= 35%
