Mathematical Expressions in JavaScript

We can perform multiple calculations using operators in the same line of code:

console.log(3 - 4 + 6); // Prints 5
console.log(5 + 2 - 3); // Prints 4
console.log(2 * 5 + 1); // Prints 11
console.log(4 / 2 * 5); // Prints 10

We can also use variables:

let num1 = 5;
let num2 = -1;

console.log(2 * num1 * num2); // Prints -10
console.log(num1 + num2 - 3); // Prints 1
console.log(20 / num1 + num2); // Prints 3
console.log(num1 / 5 * num2); // Prints -1
