Arithmetic operators take two inputs, one on either side of the operator. For instance, to add two numbers, say 2 and 5, either of the following expressions will work:
2+5
5+2
The result from this expression is "7", which must be used either in a function or variable assignment as follows:
int i=2+5;
This will not only declare variable "i", but initialize it to a value of "7".
For getting input from the user that can be used with arithmetic operators, the method will depend upon the interface you're using. If you're writing a console (text-only) application, scanf() and atoi() will work nicely:
int main()
{
int num1, num2;
printf("Enter the first number: ");
scanf("%d", num1);
printf("Enter the second number: ");
scanf("%d", num2);
printf("%d + %d = %d\n", num1, num2, num1+num2);
return 0;
}
Here, scanf() is used to read input from the user into two numbers. Then those two numbers are printed as well as the result of adding both of them.

Arithmetic operators (+, -, *, /, % ) have greater precedence over relational operators (<, >, <=, >=, ==, !=) in C language.
y=2x2+3x+1
input is the << operator and output is the >> operator
In all popular high-level programming languages, the order in which operators are interpreted ("operator precedence") is vital to ensuring that all compilers execute instructions in precisely the same manner, as the "order of operations" rule is vital in mathematics. In the case of C and C++, arithmetic operators are executed prior to logic operators. For a detailed description of operator precedence, see the related links below.

An arithmetic operator is any of the "atomic" operators to do the following math operations: + addition - subtraction / division * multiplication % modulus division
Arithmetic operators (+, -, *, /, % ) have greater precedence over relational operators (<, >, <=, >=, ==, !=) in C language.

The arithmetic operator that divides contents of a cell is the front slash. =A3/B3
Multiplication
There are two stream operators: << (insert or put) and >> (extract or get). Output streams implement the insertion operator, input streams implement the extraction operator and input/output streams implement both operators.
