Simplifying like terms in an equation is something that almost always occurs when we are going to solve it. It's enough for a first-degree equation to contain more than two or three terms for us to have to resort to this method to find the final result.

Solving equations by multiplying or dividing both sides by the same number is another useful and common method when it comes to finding the value of any type of equation.

Solving equations by adding or subtracting a number to both sides of the equation is one of the most common and useful methods for doing so. This method is very simple and easy to apply.

The first step to solving a scary, complex multiplication equation is to simplify it. Often, what seems complicated is actually fairly simple. This is where the distributive property comes to helps us! The distributive property helps us to rewrite our expressions by breaking down large numbers into smaller, more manageable chunks.

Does using the distributive property seem easy by now? Great! It's not so hard, it just takes some practice. Let's go a bit deeper - now we'll explore the *extended* distributive property. Here we'll see expressions with **two sets** of parentheses. Don't worry! Using the same principles that we've already learned, we'll find that the extended distributive property isn't any different than the basic distributive property.

The distributive property is a tool that helps us to simplify complex expressions by breaking down large numbers into smaller, simpler terms.

The quadratic function, or the parabola, is a function that we will work with a lot throughout the years of studying mathematics in high school, so it is important to understand what it means and what to expect when solving its questions.

The ratio describes the "relationship" between two or more things. The ratio links the given terms and describes how many times greater or smaller a certain magnitude is than another.

Questions about scale deal with the relationship between the actual dimensions of an object and those of the drawing that represents it.

Inverse proportionality indicates a situation in which, when one term is multiplied by a certain number of times, the second term is decreased by the same number of times and vice versa.

Direct proportion indicates a situation in which, when one term is multiplied by a certain amount, the second term undergoes exactly the same thing.

Sometimes we will be given only a whole ratio between two terms and a third piece of data that is part of another ratio. Usually, it will be stated that there is a proportion between the ratios and that we must find the missing data in the ratio.

Many students believe that proportionality is a super complicated topic, but believe me, it's not like that at all, it's entirely based on ratio or relationship and circumstances you have already studied.

In a division according to a certain given ratio, we will have a defined quantity that we must divide according to that ratio.

Equivalent ratios are, in fact, ratios that seem different, are not expressed in the same way but, by simplifying or amplifying them, you arrive at exactly the same relationship.

Did you notice the quadrilateral that is formed at the intersection of 2 train tracks? What is it called? What are its characteristics? Let's take a look at the train tracks, why are there 2 parallel tracks? For the train to not derail, there must be 2 tracks that always maintain the same distance from each other. This is the definition of parallel lines that never meet because the distance between them is always the same. At the moment when 2 train tracks intersect, a quadrilateral is formed between them, which has 2 pairs of opposite sides parallel, which is the parallelogram. In this article, we will talk about what a parallelogram is and learn how to prove it.

An integral part of the curriculum also includes geometric shapes, which feature, among other things, the rhombus. It's important to note that even if you are a high school student, you will still be asked to solve problems that include these same shapes, rhombuses included.
So, how do you calculate the area of a rhombus?

Often, when we sit on the beach facing the sea, we observe a good number of kites. Have you examined their shape? It's a deltoid shape. The deltoid has a somewhat complicated shape. It is a quadrilateral but not a square, and it has a shape similar to a rhombus and a parallelogram, but their definitions are different. In this article, we will learn what a deltoid is and how to identify it.

Percentages are one of the most studied topics in mathematics. And one of the most common exercises that every math student must know how to solve is how to calculate percentages.

More than once, we've heard the principal telling the teacher, "Have you noticed that there is no overlap between the students and the study material? Well, your goal is to create that overlap." So, what is an overlap in everyday language? Overlap is a coincidence between two or more elements. Also, when we talk about triangles, we can find different types of coincidences. There are triangles that are equal only in their angles and are called similar triangles, and there are triangles that are equal in both their angles and sides, being identical to each other. We will call these latter triangles congruent triangles, and we will learn about them in this article.

What are those mysterious square roots that often confuse students and complicate their lives? The truth is that to understand them, we need to grasp the concept of the inverse operation. What do we mean by this? When we solve an exercise like "How much is 5 squared?" it's clear that 5 multiplied by 5 gives us a result of 25. This is the concept of powers or, to be more precise, squaring a number. To apply it, we multiply the figure or number by itself. But what happens when we encounter an exercise where X squared equals 25? In this case, we must perform an inverse operation, and this is when square roots come into play.

In this article, we'll start by recalling the definition of an "exponent," and then we'll focus in an organized manner on the different rules of exponents:
