As well as displaying text, programming languages will also work out math. An example of this could be:

Earlier on in 1 - Printing Basics, I wrote that print is a function. You can tell a function in Python because it has parenthesis ( ).
| Operator | Python symbol |
|---|---|
| + | + |
| - | - |
| x | * |
| รท | / |
In the above example, Python is evaluating everything between the parenthesis. Have you noticed that 2+2 * 2 is 6? You probably learned about BIDMAS (or BODMAS) in math lessons. multiplication happens before addition in the order of operations.

A couple more operators you will need to learn are the DIV and MOD operators. These are often useful in programming and frequently come up in exam questions.
| Operator | Operator | Explanation |
|---|---|---|
| MOD | % | remainder (or modular) division only shows the remainder of any division. |
| DIV | // | integer (or floor) division removes the decimal point and remainder of any division. |
| equal to | == | This is a comparative operator. You will learn more about these in the coming lessons. It is used to compare 1 object to another object. |
