Summary  
This chapter explains how to use basic arithmetic operators (+, –, *, /) to evaluate numeric expressions directly in an interactive environment where results are automatically printed.  

General domain of usage  
Data analysis

In R, arithmetic expressions can be written directly in the console, and the result is displayed without the need for an explicit print function.

## Arithmetic Operators
You can use the following operators for basic arithmetic:
- `+` for addition;
- `-` for subtraction;
- `*` for multiplication;
- `/` for division.

### Example

Each new operation should start on a new line.

Note

Gain a solid understanding of R, one of the most widely used languages for data analysis. Explore fundamental data types and one-dimensional values, then advance to multi-dimensional structures, including matrices, data frames, and lists. Build the skills needed to apply R effectively in statistical analysis and data-driven decision-making.

Learn the essentials of R syntax, such as arithmetic, variables, printing functions, and comments. Strengthen your understanding of computational logic through exercises.

Explore R's data types and understand their role in data handling. Build skills in working with vectors as essential structures for organizing and analyzing information.

Develop the ability to manage categorical data effectively. Discover how to structure, group, and interpret values by converting raw data into clear categories.

Understand how to represent and work with structured two-dimensional data. Build confidence in transforming, labeling, and applying operations to matrices for analytical tasks.

Master the most widely used data structure in R for tabular information. Learn to organize, transform, and extract insights from datasets to support data-driven decisions.

Learn how lists extend beyond vectors by storing elements of different types and lengths. Develop the ability to create, access, and modify lists for organizing complex data structures.
