Doubt about a sentence written in english
Hello everybody,
I do not think I understand at all the structure of the following sentence:
"Had we used the centroid in place
of SUM, then we could not adjust the centroid to account for the new point
without doing some calculation involving N ...]"
What I'm wondering about is to know what kind of tense it is (past perfect or what?) and if you could give me more examples of sentences like that (conditionals or whatever). It would be much better if you could include a translation from English to Spanish; but if that is not possible, no worries.
Thank you in advance!

Question about an English Sentence.
Hello everybody,I do not think I understand at all the structure of the following sentence:
"Had we used the centroid in place of SUM, then we could not have adjusted the centroid to account for the new point
without doing some calculation involving N ...]"
What I'm wondering about is what kind of tense it is (past perfect or what?) and if you could give me some more examples of sentences like that (conditionals or whatever). It would be much better if you could include a translation from English to Spanish; but if that is not possible, no worries.
Thank you!
Very well written!

This is the so-called Third Conditional, it's basically the same as in Spanish, except Spanish uses the subjunctive in the 'if' clause:
Si hubiéramos/hubiésemos utilizado el centroide/baricentro en lugar de/del SUM, no podríamos ajustar el centroide/baricentro para dar cuenta del nuevo punto sin hacer una calculación con N.
As pointed out in the comments, 'had we used x' is another way of saying 'if we had used x', so that's the past perfect. In this example it would be more natural to say 'we wouldn't be able to adjust' because 'could' makes the phrase sound like the past tense ('could' is both the past and conditional form of 'can') but the grammar is technically correct.

1) If I had not learned Spanish, I wouldn't be here. 2) >>>>>>>>>> OK Had I (it needs the subject here) not learned Spanish, I wouldn't be here. 3) NOT GOOD >>>>>>>>>>>> If I did (did does not work here) not learn Spanish, I wouldn't be here. (This has a different meaning. You could use it, perhaps, if you were learning Spanish and actually at a Spanish class or related activity. )

Thank you Savannah! By the way, I'd be glad if you or anyone check the following phrases:
1) If I had not learned Spanish, I wouldn't be here.
2) Had not learned Spanish, I wouldn't be here.
3) If I did not learn Spanish, I wouldn't be here.
Do all of them mean the same? Are they correct?
Thank you in advance.

Tomás, it shows a relation of time between two actions.
It is similar to 'si no hubiese aprendido español, no estaría aqui. If I had not learned Spanish, I wouldn't be here.
