Any ideas why we're learning 'cifra' here?
Cyphers can be associated to numbers, but it seems like an odd choice of vocabulary. We have only seen a couple of math terms, for example. I can think of many examples of concepts that might include numbers that I would rather learn before cypher.
For those of you that are native speakers, is it possible that this word is used more frequently in Brasil? Or perhaps in a different context?
Wow. All of that? It seems more like "total" is used for total (yeah, I know it's the same word...you know what I mean). :) And isn't "soma" or something used for sum?
Now don't get me wrong, I'm all for synonyms. I am just wondering if beyond its many uses, if the word is really used all that often.
If you've previously learnt Spanish, where it's the word for 'figure' it helps to know that it can mean something different in Portuguese. Duo has included other words which mean something different in Spanish, e.g. Maestro (conductor, in Spanish teacher). Presumably since many people have started learning Portuguese here after doing the Spanish course. Spanish was the first language that Duolingo offered.
