Mathematics is one of the most necessary sciences that we must take advantage of to teach our children and also our relatives. Today, despite the fact that calculators exist in practically all smart devices, it is necessary to know some type of basic operations that will really get us out of a lot of trouble. For this reason, in this article we want to teach you and give you some tips on how to add correctly.
The term add refers, in general terms, to the fact of adding things to a basket. In fact, in our routine life we can carry out this type of operation in many areas, both at work and personal level, such as when we go shopping. Undoubtedly, making a small mistake in these cases can end up being fatal for our economy.
What is add?
The addition operation is one of those that is first learned in schools. At the mathematical level, teachers usually teach it in a way as if a house were being built. First you start with addition and subtraction and then move on to multiplication and division. Why? The reason is really simple. To know how to multiply and divide without using the calculator, it is necessary to know how to add and subtract. In this sense, all the mathematics go upwards and the complexity of each operation makes it necessary to cover and consolidate the base in order to advance correctly and at a good pace.
Therefore, the first step is to learn to add. The sums consist of adding objects of the same or different types depending on how we want to classify them. To give you an idea, if we have three apples and two pears on the table, we can say that there are a total of five pieces of fruit. However, if we want to keep the types of fruit we will have to say that there are three apples and two pears. The origin of mathematics is almost as close to that of philosophy. In fact, in the ancient deposits that can be seen in South Africa, the continent where the human species is thought to have appeared millions of years ago in ancient Pangea, there are already samples that seem typical of mathematics.
One of the first memories that scientists take into account, and obviously historians, to determine the beginning of the origin of mathematics, is a series of marks that are believed to be used by women to calculate their menstrual cycle located between 28 and the 30 days. To do this, it was necessary to know how to add, since otherwise it is practically impossible to predict correctly when the period would come to each of the girls who noted the days they spent in said brand. The hunters themselves also used the numbers zero, one and two, which is a first example of prime numbers, those that can only be divided by zero or by themselves.
The Greeks were others who made great contributions to mathematics thanks to some like Archimedes or Thales of Miletus, although most of them focused on other fields such as geometry. However, those responsible for introducing great mathematical advances in Spain were the Arabs. Despite the fact that they led to years of wars between the Hispanics and the so-called Moors, it is also true that in addition to their art, the Berbers brought new forms of agriculture, the compass and great advances in the mathematical field. Undoubtedly, history has gone hand in hand with mathematics, which currently allows us to enjoy an exact or practically science in its majority.
Benefits of Adding Correctly
All in all, knowing how to add contains important benefits for everyone who masters this basic mathematical operation. Some of the most prominent are the following:
- Make the purchase without being scammed. In the Middle Ages, the clerics were the only ones who knew how to add and, obviously, when dividing the crops, they always gave more than what was established. Therefore, if you do not want to pay more than what you have when purchasing products, it is necessary to know how to add.
- Pass math in elementary school. The sums are one of the first essential requirements to be able to pass the subject of mathematics, one of the compulsory ones that all students must pass to access the next course.
- Being able to develop a professional career. Mathematics incorporates many career paths. The main one is economics, with numerous related positions. However, as we have said before, mathematics is like building a house and the first pillars are the sums.
- To organize events. When organizing any type of event, where many people are going to attend, knowing how to add up can help you correctly supply food, as well as the guest list that allows you to control everyone who is coming.
Undoubtedly, knowing how to add is currently an essential requirement to be able to lead a life correctly and without shocks or suffering.
How to add:
When adding there are multiple procedures. In this article we will explain how to do simple sums using our brain accompanied by paper and a pen. However, technology has been placed next to humans and, in this case, it can also be of great help in performing sums. When adding we can differentiate between simple and complex operations. For example, if we want to add units, it will not be necessary to use pen and paper in most cases. For example, if we have 3 pears and five apples, we have eight pieces of fruit. This is something that someone with mathematical knowledge can know in just five seconds. However, during the first days we recommend that you use your fingers for operations whose result is less than ten.
Counting on our fingers we can decipher the result. For example, if we have eight pieces of fruit, each of them is a finger and when we reach eight we will know the final result. On the other hand, for those more complex operations we can use paper and pencil. You must differentiate each number between units, tens and hundreds. The important thing is to add each unit with its corresponding one and, in the event that there is none because the second term to be added is less, you must imagine that there is a zero. In this sense, we add units with units, tens with tens, and hundreds with hundreds. The resulting term is the result that we will get from performing said corresponding sum.
Let’s not forget the importance of knowing how to add correctly. If you want to progress in mathematics it is necessary to consolidate this knowledge. In fact, to know how to multiply without the use of a calculator, it is absolutely necessary to add correctly. To check if we are doing it correctly, we can perform the inverse operation. It is one of the advantages of having an exact science. Once we have finished the operation, it is possible to subtract the result by one of the two components of the sum. If we have done it correctly we should have the other component. For example, 5 and 3 add up to 8. If we take 3 from 8, it gives 5 and if we take 5 from 8, it gives 3. It is the way to verify that we have carried out the operation correctly.
The technology to add correctly
When we are little it is important to know how to do it manually because it will be an operation that we will have to face during our primary education. However, once we advance in our education, we will have at our disposal different technological tools that will allow us to perform sums in a simple way and without the need to make a mistake, unless we insert the terms more, nor to think about what let’s go do
On the one hand, we can find the calculator, which is not the love calculator that we can find on the Internet. Surely you have ever used one. Basically, what we must do is enter the first component of the sum, then press the + sign and then enter the next component of the operation. Finally, we will give the = and we will get the result of the operation. Remember that through the calculator you can carry out more than one operation at the same time indefinitely, so it is a great option if you want to calculate the net salary, both personally and for a family member or friends.
Finally, computer programs can also be the solution to your problem. On the one hand, we have the Windows calculator, which basically works like a normal calculator by following the same steps that we have explained above. On the other hand, Microsoft Excel can also be an option that can save us from our problem. This program is used to create spreadsheets and has numerous formulas at our service, among which the addition formula is obviously included. Therefore, if you want to know how to add accounts with multiple options that you can use. We recommend that you learn to add correctly, and that obviously, later you benefit from all the resources that you have at your disposal. Undoubtedly, the mathematical operations that you may require are solved with the multiple resources that you can exploit.
