French language Q&A Forum

In the example 1 x 2 = 2,  the translation given is « une fois deux égal deux. » I translate this as « one times two equals two. » Why is « une » used instead of « un» ?  In contrast, I see that an another possible translation is « un multiplié par deux. »

I am having a difficult time deciding when devoir is appropriate and when it is not.  All the other applications, I am ok with.  But if devoir implies "must have" why is a purse a necessity? Why not just Avoir besoin?  And why is sleep NOT a necessity (or I may be getting this confused at this point). This is getting to be more of a guessing/memorization thing than an actual understanding thing.  I see from the previous posts that this has been discussed ad infinitum so it's not just me.  Any easy way to decide when to use devoir and when NOT to use it in this context?

Thanks

Questions including sentenses like "This bedroom is grey. - Yes, it's grey here."  make absolutley no sense to me.

What is "Yes, it's grey here" referring to? The weather, or a completely different bedroom perhaps. 

As I have no idea, I have to quess and and so keep getting the answer wrong.

I would be grateful if you could tell me what the question means by using different words.

When we are using C'est plus the standalone adjective,is it always masculine and singular?on it can also be masculine and plural depending on the sentence ofcourse
