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.
