Arithematic is a branch of mathematics, that involves the study of numbers, operation of numbers that are useful in all the other branches of mathematics. It basically comprises of operations such as Addition, Subtraction, Multiplication and Division. Let us understand each of the operation in details.
Addition is denoted by ‘+’ sign. It involves combining two or more numbers into a single term. It can involve any type of number whether it be a real or complex number, fraction or decimals.
For example- 4.13 + 3.87 = 8
The addition of more than two numbers , values or terms is also known as summation of terms and can involve n number of values.
Subtraction is denoted by ‘-‘ sign. It is almost similar to addition but is the conjugate of the second term. The addition of term with the negative term is known as subtraction.
Example: 15 – 7
The term can also be re-written as 15 + (-7)
Additing terms we have, 8.
Multiplication is denoted by ‘\(\times\)‘ or by ‘*’ ,It also combines with the two or more values to result into one a single value.
Product of two numbers, say ‘a’ and ‘b’ result in a single value term ‘ab,‘ where a and b are the factors of the final value obtained.
Division is usually denoted by ‘\(\div\) or /‘ and is the inverse of multiplicaiton. It constitutes two terms divident and divisor, where divident is divided by divisor to give a single term value.
When the divident is greater than the divisor, the result obtained is greater than 1, or else it would be less than 1.
