French language Q&A Forum

In comparing these three sentences, I notice that the verbs have similar translations (is/are getting or becoming):

Ses relations avec elle vont de mal en pis

Ma mémoire est de pire en pire

Les ordinateurs deviennent de mieux en mieux

Can these three verbs be used interchangeably with these expressions to mean is getting/going/becoming worse or better? Or is there a distinction to be made?

Thanks for your help!

Salut! Would “trop” be accepted instead of “si” in the sentences. I used it in both the sentences in the passage but they were corrected to “si”. Is there a difference? Thank you 

In the examples given, 

C'est pratique, les ciseaux. 

There is an adverb and a noun. Why would this not be ce sont? is les ciseaux similar to par of jeans? Where it is plural but acts singular? If this is so it is a slightly confusing example. Thank you.
