Dart Arithmetic Operators

Arithmetic Operators

Arithmetic Operators are used to perform basic mathematical arithmetic operators like addition, subtraction, multiplication, etc. The following table lists out all the arithmetic operators in Dart programming.

Operator	Symbol	Example	Description
Addition	+	x+y	Returns addition of x and y.
Subtraction	–	x-y	Returns the subtraction of y from x.
Multiplication	*	x*y	Returns the multiplication of x and y.
Division	/	x/y	Returns the quotient of the result of division of x by y.
Division	~/	x~/y	Returns the quotient of the result of integer division of x by y.
Modulo	%	x%y	Returns the reminder of division of x by y. Known as modular division.
Increment	++	x++++x	Increments the value of x by 1.
Decrement	—	x----x	Decrements the value of x by 1.

Example

In the following program, we will take values in variables x and y, and perform arithmetic operations on these values using Dart Arithmetic Operators.

main.dart

void main() {
    var x = 5;
    var y = 2;

    var addition = x + y;
    var subtraction = x - y;
    var multiplication = x * y;
    var division = x / y;
    var division_1 = x / y;
    var modulus = x % y;

    print('x + y = $addition');
    print('x - y = $subtraction');
    print('x * y = $multiplication');
    print('x / y = $division');
    print('x ~/ y = $division_1');
    print('x % y = $modulus');
    print('x++ = ${++x}');
    print('y-- = ${--y}');
}

Output

x + y = 7
x - y = 3
x * y = 10
x / y = 2.5
x ~/ y = 2.5
x % y = 1
x++ = 6
y-- = 1
