◉ Exponential Notation.
Answer: 6⁴, 3², 4⁶
◉ Standard Notation.
Answer: 5² = 25
25 is the standard notation
( answer to solution )
◉ Adding or Subtracting fractions.
Answer: requires a common denominator
◉ Multiplying fractions.
Answer: no special rules, multiply across
( ex: ⅗ ⋅ ⅚ = ½ )
◉ Dividing fractions.
Answer: multiply by the reciprocal
,( ex : 1/4 ÷ 5/3 = 1/4 ⋅ 3/5 )
◉ 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
