Arithmetic Operations
Learn about the arithmetic operation with examples.
We'll cover the following...
Most programming languages can carry out all the usual arithmetic operations—just like a pocket calculator. Calculations can be set out as we would expect, and they often use the operators and symbols we’re familiar with. JavaScript is no exception. Let’s try doing some math in the below widget.
Addition
Addition uses the + operator, as we would expect:
console.log(5 + 4.3);
This example shows that we can mix integers and floats in calculations.
Subtraction
Subtraction uses the - operator, and there are no problems dealing with negative numbers:
console.log(6 - 11);
Multiplication
Multiplication uses the * operator:
console.log(6 * 7);
Division
Division uses the / operator as if it was a fraction:
console.log(3 / 7);
This answer should actually be a recurring decimal, but JavaScript will truncate the answer (usually with a slight rounding error at the end).
Exponentiation
Exponentiation can be carried out using the ** operator. The following code will return ...
