# Les 5a

**Voorrangsregels**

Heb je al eens geprobeerd om een som te maken met verschillende operatoren erin? 5 + 4 - 2 dat gaat wel goed, maar als je keer en plus mixt, dan krijg je een verkeerd antwoord! Bijvoorbeeld 5 + 4 \* 10. Het goede antwoord hier is natuurlijk 45. Want 4 \* 10 gaat voor, dat wordt 40 en dan moet de 5 er nog bij opgeteld worden. Maar onze rekenmachine weet dat nog niet. Die gaat gewoon van links naar rechts en maakt er dus 90 van: 5 + 4 wordt 9 en dan keer 10. Dat gaan we deze les oplossen!

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://felienne.gitbook.io/codasium/module-2.3-rekenmachine/les-5/les-5a.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
