Dart Operators: Arithmetic

In Dart, arithmetic operators are used to perform mathematical calculations on numerical values. Here are the arithmetic operators available in Dart:

1. Addition (+):

   • Adds two operands.

   • Example: int sum = 3 + 5; // sum is 8

2. Subtraction (-):

   • Subtracts the right operand from the left operand.

   • Example: int difference = 8 - 3; // difference is 5

3. Multiplication (*):

   • Multiplies two operands.

   • Example: int product = 3 * 5; // product is 15

4. Division (/):

   • Divides the left operand by the right operand.

   • If both operands are integers, the result is an integer (integer division), and any fractional part is discarded.

   • If at least one operand is a double, the result is a double.

   • Example: double quotient = 10 / 3; // quotient is 3.3333...

5. Modulo (%):

   • Returns the remainder of the division of the left operand by the right operand.

   • Example: int remainder = 10 % 3; // remainder is 1

Here's a simple example demonstrating the use of arithmetic operators in Dart:

void main() {
  int a = 10;
  int b = 3;

  int sum = a + b; // 10 + 3 = 13
  int difference = a - b; // 10 - 3 = 7
  int product = a * b; // 10 * 3 = 30
  double quotient = a / b; // 10 / 3 = 3.3333...
  int remainder = a % b; // 10 % 3 = 1

  print('Sum: $sum');
  print('Difference: $difference');
  print('Product: $product');
  print('Quotient: $quotient');
  print('Remainder: $remainder');
}

Output:

Sum: 13
Difference: 7
Product: 30
Quotient: 3.3333333333333335
Remainder: 1

These arithmetic operators are fundamental for performing mathematical calculations in Dart programs.
