PEMDAS - ANSWER -(parenthesis, exponents, -Named using any two point on a line w a two sided arrow above
multiplication, division, addition, subtraction) work left to right them
-It can also be named using a lower-case cursive letter
Exponential Notation - ANSWER -Ex: 6^4, 2^3, 9^10, etc.
Collinear Points - ANSWER -Points that are on the same
line
Expanded Form - ANSWER -Ex: 7x7x7, 6x6, 2x2x2x2x2,
etc.
Plane - ANSWER --A plane has two dimensions
-It is represented by a shape that looks like a floor or a wall, but
Standard Notation - ANSWER -Ex: 5^2= 25; 25 is the it extends w/o an end
standard notation (the answer or solution) -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
+x+ - ANSWER -=+
Coplanar points - ANSWER -Points that lie in the same
+x- - ANSWER -=-
plane
-x- - ANSWER -=+
Line Segment - ANSWER -A line segment is named using
both end points with a line above them
Adding or Subtracting fractions - ANSWER -You need a
common denominator
Ray - ANSWER -A ray is named using its endpoint first
and then any other point on the ray pointing to the right above
them
Multiplying fractions - ANSWER -no special rule, just
multiply Ex: 2/5 x 3/9= 6/45
Intersecting lines - ANSWER -2 lines that share exactly
one point
Dividing fractions - ANSWER -flip 2nd fraction and multiply
Ex: 2/5 divided by 3/9= 2/5 x 9/3
Parallel lines - ANSWER -2 lines that are always the same
distance apart and never touch
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
Perpendicular lines - ANSWER -The relationship between
fraction
2 lines which meet at a right angle (90degrees). Perpendicular
lines= 2 lines intersect at a right angle
Percent Increase or Decrease problems - ANSWER -
Formula: amount of change/ original number. Ex: Find the
Right angle - ANSWER -90 degrees
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%
Straight angle - ANSWER -180 degrees
Interest - ANSWER -Formula: interest= principal x rate x
time (I= PxRxT) Acute angle - ANSWER -between 0 degrees and 90
degrees
Point - ANSWER --A point has no dimension
-It is represented by a dot Obtuse angle - ANSWER -between 90 degrees and 180
-A point is written using an upper-case letter degrees
Line - ANSWER --A line has one dimension Complementary angles - ANSWER -2 angles that have the
