# What does 1 + 1 mean?

When we talk about “1 + 1”, we are referring to a basic addition of addition. In this case, we are adding number 1 with number 1.

## Addition Operation

Addition is one of four fundamental operations of mathematics, along with subtraction, multiplication and division. It consists of combining two or more numbers to get a result called sum.

### Example:

If we have 1 apple and earn 1 more apple, when adding these quantities, we will have a total of 2 apples.

mathematically, we can represent this operation as follows:

** 1 + 1 = 2 **

Here, number 1 is called “first term” and number 1 is called “second term”. The sum of these two terms results in number 2, which is called “sum” or “result”.

## Use of addition

Addition is an operation widely used in various situations of our daily lives. It allows us to combine quantities, add financial values, calculate distances, among other applications.

In addition, addition is the basis for the development of more complex mathematical concepts, such as multiplication, potentiation and algebra.

## Conclusion

In short, when we refer to “1 + 1”, we are talking about the addition operation, which consists of adding number 1 with number 1 to obtain the result 2. This is a fundamental operation of mathematics and has various applications in our daily lives.
