Pre - Algebra
In math, we are learning about inequalities and how to graph them. What you do first for the inequalities, if you have to find the variable you do the opposite of the sign there is. If you are using the sign without the line at the bottom, it means that the inequality could be less, or greater than. We are also learning how to graph inequalities. I learned that when you graph inequalities, you have to look for the sign at the bottom. If it has a line under the sign, it would be a closed dot. Also if there is no line under the sign, it will be an open dot. Also we were solving multi-step inequalities. For example, 2x+6 < 44 you will first have to subtract 6 to both sides. The you will have 2x < 44 you will then have to divide both sides by two and you will get x < 22. You will graph it after.
We are currently learning about monomials and exponents. Exponents and monomials are really easy for me. Exponents are the numbers that have the power number on top. Monomials are the numbers you have to solve for. There are rules for exponents though. Some rules are that when you see a 2 and a 3 on top of it that doesn't mean 2 times 3, it means 2 times 2 times 2. Monomials are like (2x) 3 that equals 2 times 2 times 2 times 2. These are some things we are learning in class.

My PresentationIn math we are doing a project and we have to do a presentation. We have to add many things on the presentation. We have to pick a topic from a packet we did. Then we have to present the topic and put it in a presentation. You have to show the steps on each question you did and then present your presentation.

Pythagorean Theorem
Graphing Linear Equations
The first thing you have to do to graph linear equations is write an equation first. Then you would solve the equation and then graph. For example, the equation is y=3x+1. You can use whatever numbers and make a chart to keep track of your answers so you can then graph them.
Inequalities
In math, we are learning about inequalities. We are graphing and finding if they are greater than, less than, less than or equal to, or greater than equal to. What we first do to graph the inequalities is you have to figure out what the sign is. So if the sign is pointing to the right/left and has the line on the bottom, that means that when you graph the inequality it will be a closed dot pointing to whatever you get. If the there is the sign that points to the right/left and doesn't have a line on the bottom, then that means that when you graph the inequality it will be an open dot. When you have an inequality that has more than one step you solve it before you graph. For example, when it is like 2x-5 > 33 you will first need to subtract 5 to both sides because you want to get the variable by itself. The you will divide both sides by two and then you can graph your inequality on the number line. Remember that when there is a line on the bottom of an inequality it is a closed dot, and an inequality without a line on the bottom it is an open dot.
I learned the difference between the sign that has a line at the bottom and the one that doesn't. I also learned how to graph the inequalities. I think that inequalities are really important because if you want to be a math teacher you have to pay attention about the stuff you learn. Also I learned the rules of graphing inequalities with and without the line at the bottom of the sign. I also learned that when you graph inequalities you have to pay attention in which way the line has to point at and if it is a closed or an open dot. The tools we used were pencils, paper, etc. I also learned how to solve multi-step inequalities in order.
