Mathematical Assignment Operators

Mathematical Assignment Operators are used to perform arithmetic operations and assign the result back to the same variable.

The most common Mathematical Assignment Operators are:

• Addition Assignment Operator += It adds the value on the right-hand side to the value on the left-hand side and assigns the result back to the variable.

  Example:

  1let num = 10;
  2num += 5; // equivalent to num = num + 5;
  3console.log(num); // Output: 15
  

• Subtraction Assignment Operator -= It subtracts the value on the right-hand side from the value on the left-hand side and assigns the result back to the variable.

  Example:

  1let num = 20;
  2num -= 7; // equivalent to num = num - 7;
  3console.log(num); // Output: 13
  

• *Multiplication Assignment Operator: = The multiplication assignment operator *= multiplies the value on the right-hand side with the value on the left-hand side and assigns the result back to the variable.

  Example:

  1let num = 5;
  2num *= 4; // equivalent to num = num * 4;
  3console.log(num); // Output: 20
  

By using these mathematical assignment operators, we can perform arithmetic operations in a concise and efficient manner while assigning the result back to the variable.
