Define Factor.....

• A number that can only be divided by itself and one

• Clearly defined set of objects

• Multiple of a given number

• This is a number that divides into another number exactly, without leaving a remainder.

Define set......

• This is a clearly defined set of objects

• The number of elements in a set

• Elements in neither sets

• This is when we compare a part to a total

Define Cardinal Number:

• An odd number

• This is a clearly defined set of objects

• This is the number of elements in a set

• The intersection of two sets

Define Proportion:.....

• This is when one quantity increases the other quantity

• This is when we compare a part to a total

• This means that something is the same shape as another but a different size

• This is when we compare one part to another

Define Ratio:

• This is a line that intersects parallel lines

• This is when we compare one part to another

• This means that something is the same shape as another but a different size

• Whole positive numbers

Define Inverse Proportion:

• This is when one quantity increases the other quantity decreases

• When a fraction has a bigger number on the top than bottom

• This is when we compare one part to another

• When a fraction has a smaller number on top then bottom

Define Similar:

• When two shapes are the exact same

• This means that something is the same shape as another but a different size

• When we compare one part to another

• This is when an element is in both sets

Define Transversal:

• An angle between 90 and 180 degrees

• This is a line that intersects parallel lines

• A line that travels to infinity in both directions

• A line that has an end point but goes to infinity in the other direction

Define Parallel Lines:

• Two lines that make a 90 degree angle at their point of intersection

• When more than two lines intersect at a certain point

• These are lines that never meet

• Two lines that intersect at a certain point

Define Roots:

• These are the solutions to an equation

• Numbers that can not change in value

• A collection of terms

• Numbers in front of variables
