Answer:
Property of subtraction
Step-by-step explanation:
This is when you see a addition sign but because you need to get rid of a number on one side you subtract so it will be gone.
First you'll need to find the line of symmetry using the formula x=-b/2a. In this case, you have x=-(4/3)/(2*(-1/3))=(-4/3)/(-2/3). Then take this x value and plug it into your equation to get a y-value. This will be your vertex. Now what I like to do to get the other 2 points needed to graph the parabola is pick an x value 1 unit left of the vertex x value and another x value 1 unit right of the vertex x value. That will give you two points on either side of the vertex, and connecting the three points will create your parabola.

If it's 5 and above, give it a shove
If it's 4 and below, leave it alone
Basically if the number is 5 or above, it goes up to the next number
If it's 4 and below, it's rounds down
