##
When working with inequalities where the product of 2+ variables is compared to 0...

Z^2(y)<0

###
...remove the even powered terms to simplify the expression

Z^2(y) < 0 becomes y<0

2

## To take the distance between two points

###
Take the absolute value of their difference

(Distance between -4 and 5 = |-4-5| = |-9| = 9

3

## To solve the distance between 2 points that involve intervals with even numbers

### Distance/ Number of intervalos = Length of interval

4

## Number of tick marks in relation to intervals (on a number line)

### Number of tick marks will always be 1 greater than number of intervals

5

## If the order of points on a number line is not mentioned...

###
...do not assume a specific order,

(Could be A, B, C, could be A, C, B, etc.)
