use of and/or operators

[Former user]

Not sure if this is a bug but typing "3 and 5" gives 15, ie it seems to be doing 3*5. The same happens if you type "3 or 5".

[cee]

Logical AND is to be used in one of the following ways :

and(3;5)

3 & 5

‌

The latest version from source does raise an error when used like “3 and 5”.
