Arithmetic Operators

Basic arithmetic often comes in handy when programming. These include the following operators and their corresponding symbols:

• Addition +
• Subtraction -
• Multiplication *
• Division /
• Modulus %

The first four work how you might guess:

1console.log(1 + 2); // Prints 3
2console.log(3 - 2); // Prints 1
3console.log(9* 2); // Prints 18
4console.log(6 / 3); // Prints 2

The Modulus (%) operator returns the remainder of a division operation. Example:

1let remainder = 17 % 3;  // remainder = 2
