Algebra Problems Have Their Own Structure
Just like an essay or research paper, an algebra problem and its solution have their structures. You should now not only provide the answer, but to describe the process as well as interpret the received results.
You have to remember how to organize lengthy problems. Difficult problems with many possible solutions may take plenty of your time. To avoid mistakes, it is critical to organize the process by beginning with the new number line each time it is possible to take a new step toward a solution. When you work on a two-sided equation, it is recommended to put down each symbol of equality underneath each other. That is a great approach to avoiding mistakes or fixing them later.
E.g. to cope with the equation 10/5 1 + 4 x 3, we may structure the entire solution this way:10/5 1 + 4 x 310/5 1 + 121 + 1213
Any algebra problem can be resolved in such a way. A step-by-step method is always effective, so dont forget about it when learning algebra.

Basic Points In Algebra
Lets go into some details. You may wonder what PEMDAS is in algebra. Well, it is a helpful instrument for memorizing the specific system and order of operations. You may find out how to use the order of operations by reading the corresponding article. In brief, this order refers to:
If you wish to know why the order is so critical in algebra, you must realize that working with operations in the wrong order can influence the response from the negative aspect. For example, in case you deal with the issue like 7 + 3 x 4, if you decide to add 3 to 7 before the multiplication process, youll receive 40, which is the incorrect answer. By all mathematical rules, people should conduct multiplication before addition. This way, youll obtain 19, which is a correct answer to the given problem. So, mind your order of operations!

How Does The Cancelling Principle Work
Make an attempt to obtain the variable by itself. Algebra equations have either numbers, variable, or both on two sides. If you must solve x + 4 = 8 x 3, learn to place and analyze the variable all alone. To do so, it is important to delete + 4 value. Subtract 4 from the first side. Youll stay with x = 8 x 3. Still, to get both sides equal, you will have to subtract 4 from the second side. Thus, youll get x = 8 x 3 4. By sticking to the generally accepted order of algebraic operations, a student should multiply before subtracting. The answer is x = 24 4 = 20. Its just this easy!
You may want to find out how to cancel addition with subtraction. Obtaining the unknown value by itself on the first side refers to replacing the numbers next to it on the other side of the equation. It looks like the opposite operation. On the whole, addition and subtraction are opposites as you could notice from the example below. It is one of the basic rules you should memorize when learning algebra.
The same principle works with multiplication and division. Thus, it becomes simpler to learn algebra even without any free help.

The Fundamental Principle Of Equation
Before we go about solving for the variable k, theres just one simpleprinciple of equations that we need to grasp. Since we know that both sides ofthe equation are the same, whatever we do on one side , if we dothe same to the other side, and the result is still an equation – that means both sides would still be equal. For example, wecan do any of these:
5 + k – 2 = 2 × 4 – 2 5 + k + 4 = 2 × 4 + 4 × 3 = × 3
Solving Our First Equation
Now we are ready to tackle our first algebra equation. What we want to dois to isolate the variable k on one side of the equation. Lets start with theequation: 5 + k = 2 × 4
We can see that on the left side, theres an extra 5 addedto k. So we must get rid of the 5 to isolate k. We can do this be subtracting 5from the left side. Remember that we must do the same thing to the right side to maintain equality:
5 + k – 5 = 2 × 4 – 5
Now we are almost done solving our first algebra equation!
Looking at the left side
5 + k – 5, the two 5s would cancel out, leaving us with:
k = 2 × 4 – 5
So we only need to do the arithmetic on the right side:
k = 2 × 4 – 5
k = 8 – 5
k = 3
Voila! We have solved our first algebra equation! Remember, the goal is to get the variable alone by doing the same thing to each side of the equation.
With this you have a good understanding of basic algebra, and now you should be able to solve other equations like 6 + k = 11 or 11 – m = 7. Otherwise, you may want to re-read this lesson.

Algebra is a serious subject, and it is often referred to as the “gatekeeper” for all of the other levels and a prerequisite to comprehending other levels.
At this stage, it is important to get a firm grip on theory, while at the same time practicing as much as possible. You can throw graphics and pictures out the window as they might be intrusive. Clean and straight-to-the-point text is what matters.
Math Planet does a great job at presenting example math problems. It provides an instructional YouTube video at the end of every lesson for further explanation. Additionally, you can take your knowledge and put it to practice on the SAT and ACT section of the site.
