Answer: While I am not in your class and can not unfortunately specifically help with this I can still give you a basic overview of what you need to know in most pre algebra courses and you can hopefully then use this information in the best way possible.
Step-by-step explanation: Some of the basic pre algebra concepts include:
Knowing your basic addition, subtraction, multiplication, and division. I am assuming you know how to do this sort of math. For example, I mean problems such as 5+4 or 10/5, but if you do need help with these just ask me and I can help you further.
Basic variable usage: This means being able to solve problems such as x + 10 = 15. I can help walk you through this sort of problem. The variable (which is usually represented by the letter x) is used as a placeholder for an unknown number that you need to solve for. You can think of this more simply in the example I gave as What plus 10 is equal to 15. That might help you get the basics down if you can think of a problem that way. As you can probably tell now the answer would be 5. There may be also more advanced problems regarding variables but not all pre algebra classes will include this material so if you need a review in this you can ask me as well.
Another basic concept is the concept of solving equations. This can also mean using both addition and multiplication within one equation or things of that nature. These equations can look something like 18 - (5 + 3^2) + 7 and I can help walk you through a problem like this. An important fact to remember is the order of operations, which is the way in which you must solve more complex equations like this or if you need to think of it another way it can mean the way you break down an equation. You probably have heard of PEMDAS before and this is the way you can remember the order of operations. It is an acronym with each of the letters representing an operation. P = parenthesis E = exponents M = Multiplication D = division A = addition and S = subtraction. Now we can use this to solve the equation! First we should start within the parenthesis so lets only look at that portion of the problem for now to keep things simpler. Inside the parenthesis it said 5 + 3^2 We see addition and exponents within the parenthesis so because of PEMDAS we should start with the exponent. Exponents just mean the amount of times you need to multiply the base number by itself. The base number is the number the exponent is "attached" to. Our base number is 3 and the exponent is 2 which means we should do the following math 3 * 3 which equals 9 Now we can go back to our original problem inside the parenthesis. In place of the 3^2 we can instead put 9 now as we know its the answer for that part of the problem. What we have now is 5 + 9 and we can simply add that to get 14. This means inside the parenthesis we can replace with just the number 14 as we have already solved everything we need for it. The equation now looks like --> 18 - (14) + 7. Now what we have left is addition and subtraction. Remember on PEMDAS how multiplication and division were next to each other along with addition and subtraction? For these 4 just because they are next to each other does not dictate the other rather when you are dealing with either just multiplication and division in a problem you work left to right and the same goes for addition and subtraction and since our resulting problem only has addition and subtraction left we will simply just work from the left of the equation to the right. Our problem as of now is 18 - (14) + 7. 18 - 14 = 4 so we can now have the equation be 4 + 7 and after adding we get our answer which is 11! I hope you were able to follow along with that and my explanations were satisfactory.
Hopefully at least some of this included in your module 4 but if you would elaborate more I would more than happily assist you more so please do not hesitate to reach out :)
