Recently I had this doubt about the order of precedence of mathematical operations multiplication and division. Given that we have a simple question like this

```
80 / 10 * 5

```

without parenthesis, what should be the answer? 

Should it be `40` considering both multiplication and division has the same precedence and they should be operated in a left-to-right manner in this situation?

Or

Should it be `8/5` given that multiplication has precedence over division?
