This was my favorite because it involves combining like terms which is really easy for me.
example:
(3x^2 + 2x - 4) - (4x^2 - 3x + 9)
(3x^2 + 2x - 4) + -4x^2 + 3x - 9
-x^2 + 5x - 13

One thing I learned about equations of lines is that there are two ways to solve them either by substitution or elimination. I find substituting easier because elimination has a lot of rules.
A real world example would be finding the number of items sold based the amount sold in that day and their individual cost.

What I remember about multiplying and dividing is that you have to add the exponents when multiplying and subtract when dividing.
These rules make things go faster than individually putting them together.
example:
(3x^6)(4x^2)
12x^8

on the last discussion i used a field goal as an example for a quadratic. But another example that could use a quadratic equation is if you want to find the curve of your banana for some reason. That's a real problem in today's society! The wideness of the curve would be based on your a in the equation.

Statistics was not my favorite module because the formula for standard deviation and z-score were hard to remember.
did like though that you could connect it to real life problems, like sports.
Standard deviation is good for measuring consistency in players, to see if they did better or worse in a game based on their average.
