Arithmetic is the **study of numbers**. Arithmetic is a branch of mathematics and its study involves the **basic operations of arithmetic** that are addition (+), subtraction (-), multiplication (xo *) and division (÷ or /).

## Basic arithmetic

Arithmetic operations are the various combinations that are made with the numbers, classified as:

### Direct arithmetic operations

- This group includes the
**sum or addition (+)**that is represented as the sum of two elements or more elements such as a + b + c, etc. reaching the total sum. - In this group there is also the
**multiplication (xo*)**that is represented as the product of two or more numbers such as: axb = p. - The
**enhancement**is a high number to another number, or a number (base) multiplied by the same number of times n (exponent). For example ‘a’ raised to 3 or a³ is the result of (axaxa).

### Indirect arithmetic operations

They are considered indirect arithmetic operations because it is the opposite of direct arithmetic operations.

- This
**subtraction**includes**subtraction or subtraction (-)**that is represented as the decrease of two or more numbers such as a – b – c, etc. - The
**division**is represented by a base number (dividend) that is divided by another divisor number whose result is called a quotient. It is the inverse operation of multiplication such as 6 ÷ 2 = 3 and if we invert the operation it would be 3 x 2 = 6. - The
**filing**is the root of a number (√) and inverse of the potentiation. It is represented as for example as the square root of 25 would be 5 because 5² or 5 x 5 = 25. - The
**logarithmation**is represented as the logarithm based on n and is also an inverse operation to the potentiation.
