    JavaScript provides a variety of arithmetic operators that perform mathematical operations on numbers. These operators can be used with literals, variables, or expressions.

    Basic Arithmetic Operators

    • Addition (+): Adds two numbers or concatenates two strings.

    let x = 5 + 2; // 7
    let y = "Hello" + " World"; // "Hello World"
    Cóipeáilte!

    • Subtraction (-): Subtracts the second number from the first.

    let x = 5 - 2; // 3
    Cóipeáilte!

    • Multiplication (*): Multiplies two numbers.

    let x = 5 * 2; // 10
    Cóipeáilte!

    • Division (/): Divides the first number by the second.

    let x = 5 / 2; // 2.5
    Cóipeáilte!

    • Modulus (%): Returns the remainder of the division of two numbers.

    let x = 5 % 2; // 1
    Cóipeáilte!

    • Exponentiation ()**: Raises the first number to the power of the second.

    let x = 5 ** 2; // 25
    Cóipeáilte!

    Increment and Decrement Operators

    • Increment (++): Increases a number by one.

    let x = 5;
    x++; // 6
    Cóipeáilte!

    • Decrement (--): Decreases a number by one.

    let x = 5;
    x--; // 4
    Cóipeáilte!

    Unary Operators

    • Unary Plus (+): Converts a non-number to a number.

    let x = +"3"; // 3
    Cóipeáilte!

    JavaScript Arithmetic - W3Schools

    The numbers (in an arithmetic operation) are called operands. The operation (to be performed between the two operands) is defined by an operator.
    Arithmetic Operations

    A typical arithmetic operation operates on two numbers. The two numbers can be literals: or variables: or expressions:

    Exponentiation

    The exponentiation operator (**) raises the first operand to the power of the second operand. x ** y produces the same result as Math.pow(x,y):
