PEMDAS Answer: (parenthesis, exponents, multiplication, division, addition,
subtraction) work left to right
Exponential Notation Answer: Ex: 6^4, 2^3, 9^10, etc.
Expanded Form Answer: Ex: 7x7x7, 6x6, 2x2x2x2x2, etc.
Standard Notation Answer: Ex: 5^2= 25; 25 is the standard notation (the answer or
solution)
+x+ Answer: =+
+x- Answer: =-
-x- Answer: =+
Adding or Subtracting fractions Answer: You need a common denominator
Multiplying fractions Answer: no special rule, just multiply Ex: 2/5 x 3/9= 6/45
Dividing fractions Answer: flip 2nd fraction and multiply Ex: 2/5 divided by 3/9= 2/5 x
9/3
Solving Equations w/ fractions Answer: 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 Answer: 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%
Interest Answer: Formula: interest= principal x rate x time (I= PxRxT)
Point Answer: -A point has no dimension
-It is represented by a dot
-A point is written using an upper-case letter
Line Answer: -A line has one dimension
-Named using any two point on a line w a two sided arrow above them
-It can also be named using a lower-case cursive letter
Collinear Points Answer: Points that are on the same line
Plane Answer: -A plane has two dimensions
-It is represented by a shape that looks like a floor or a wall, but it extends w/o an end

, -Through any three points not on the same line there is exactly one plane
-A plane is written using 3 non-collinear points or with upper-case cursive letter
Coplanar points Answer: Points that lie in the same plane
Line Segment Answer: A line segment is named using both end points with a line
above them
Ray Answer: A ray is named using its endpoint first and then any other point on the ray
pointing to the right above them
Intersecting lines Answer: 2 lines that share exactly one point
Parallel lines Answer: 2 lines that are always the same distance apart and never touch
Perpendicular lines Answer: The relationship between 2 lines which meet at a right
angle (90degrees). Perpendicular lines= 2 lines intersect at a right angle
Right angle Answer: 90 degrees
Straight angle Answer: 180 degrees
Acute angle Answer: between 0 degrees and 90 degrees
Obtuse angle Answer: between 90 degrees and 180 degrees
Complementary angles Answer: 2 angles that have the sum of 90 degrees
Supplementary angles Answer: 2 angles that have the sum of 180 degrees
the sum of the angle measures in a triangle Answer: 180 degrees
Acute triangle Answer: All angles are acute
Right triangle Answer: One angle is right
Obtuse triangle Answer: One angle is obtuse
Scalene triangle Answer: All sides have different lengths
Isosceles triangle Answer: At least 2 sides have the same length
Equilateral triangle Answer: All sides have the same length
The sum of the lengths of a triangle Answer: The sum of the lengths of any two sides of
a triangle must be greater than the length of the third side
Polygon Answer: A polygon is a closed figure whose sides are line segments that do
not cross
Regular Polygon Answer: A regular polygon is a polygon where all of the sides have
equal lengths and all of the angles have equal measures
Trapezoid Answer: One pair of opposite sides are parallel
