The following table shows all the arithmetic operators supported by F# language. Assume variable A holds 10 and variable B holds 20 then −

Operator Description Example
+ Adds two operands A + B will give 30
- Subtracts second operand from the first A - B will give -10
* Multiplies both operands A * B will give 200
/ Divides numerator by de-numerator B / A will give 2
% Modulus Operator and remainder of after an integer division B % A will give 0
** Exponentiation Operator, raises an operand to the power of another B**A will give 2010

## Example

```let a : int32 = 21
let b : int32 = 10

let mutable c = a + b
printfn "Line 1 - Value of c is %d" c

c <- a - b;
printfn "Line 2 - Value of c is %d" c

c <- a * b;
printfn "Line 3 - Value of c is %d" c

c <- a / b;
printfn "Line 4 - Value of c is %d" c

c <- a % b;
printfn "Line 5 - Value of c is %d" c
```

When you compile and execute the program, it yields the following output −

```Line 1 - Value of c is 31
Line 2 - Value of c is 11
Line 3 - Value of c is 210
Line 4 - Value of c is 2
Line 5 - Value of c is 1
