Mathematical rules applicable in everyday life

Mathematics is applicable in everyday life. As much as we insisted during our childhood and our school years, in which so many numbers and formulas would not accompany us until our adulthood, we were wrong, because the truth is that we can take advantage of them in many fields.

Let’s start with something basic. Who does not know the popular rule of 3? For those who do not remember this simple equation, we will specifically comment on how it works before revealing one of its most common day-to-day applications.

The rule of 3 is used to solve proportionality problems in which we have three values ​​that we know and one unknown. The objective is to find the fourth term that we will call D, and for this if we know the value of A, B and C, we must multiply C by B and divide it by A. For this rule to be fulfilled, the values ​​of A and B must be directly proportional, just as those of C and D should be.

Okay, and what are so many numbers and letters for? The most frequent example is its application in the kitchen. We know that in confectionery certain measurements must be met or the result could be a real disaster. In this case, if we have a recipe designed for 4 people and we need to feed 12, it would be enough to make a rule of three to know what quantities we have to put in our mixture.

For example, if 200 g of sugar are needed for 4 people, for 12 people we will need “x”. We will obtain the result by multiplying 200 by 12 and dividing the result by 4.

But it is clear that mathematics is not only in the world to make cupcakes and birthday cakes. We also appreciate it, but they are used for bigger things like giving answers to questions that humanity has been asking for years. For example, researchers recently discovered a mathematical principle that explains how connections are made between cells to form organs and tissues.

In our day to day, we do not need to know how organs are formed, but it is interesting to know to understand how far mathematics can go.

Application of mathematics in everyday life

We must start from the basis that without mathematics neither Google, nor the popular e-commerce company Amazon, nor any other computer application would exist, since they are generated based on something called linear algebra, although that is another story.

What we are going to in this article is certain mathematical theories that are easier to understand than the great logarithms and that we apply, sometimes, even without realizing it.

Starting with the popular Fibonacci sequence, which is now better known due to its application in the world of cryptocurrencies. Let us remember that it is an infinite mathematical sequence that is built by always adding the last 2 numbers of the series. That is, each number is equal to the sum of its previous two. Well, in the panorama cryptothe traders Professionals make use of this sequence to “try to prevent” the behavior of digital assets.

And we say “try to prevent” because most digital assets that exist today are volatile and unpredictable. In the end, the trader who uses Fibonacci for his operations will have to make a decision.

Therefore, this other rule that we are going to mention next is even more relevant, since it helps to make decisions for practically everything. Is about the 37% rulea theory disclosed by the British doctor Hannah Fry, who studied mathematics at University College London and who states that, if you have to decide between 100 options, you should immediately discard the first 37 to establish a reference standard.

After those 37, an option will appear that does meet that standard.

These are just a couple of examples of applicable theories in our daily lives, but let’s remember that mathematics also are hidden in our day to day and they give explanations to various enigmas such as, for example, why the helmets of cyclists in a time trial have changed shape in recent years.
