Questions & Answers about Нельзя играть в бильярд без того, чтобы не рассчитать угол.
Why is there a не in чтобы не рассчитать when the English translation has no negative word there?
The Russian construction без того, чтобы не always includes the negative particle не, even though it translates smoothly to 'without doing [something]' in English. You can think of the literal Russian logic as 'without that, in order not to [do something].'
Since this lesson covers using both the past tense and the infinitive with this construction, why do we use the infinitive рассчитать here?
In Russian, whenever a subordinate clause with чтобы shares the same subject as the main clause, we use the infinitive. Here, the impersonal нельзя implies a general 'you' or 'one' who is both playing billiards and calculating the angle, so the infinitive is required. If a different person were doing the calculating, you would use a subject and the past tense.
Why does this sentence use the imperfective verb играть (to play) alongside the perfective verb рассчитать (to calculate)?
The imperfective играть is used because it refers to the general, ongoing process of playing the game. In contrast, рассчитать is perfective because it describes a specific, completed result—successfully figuring out the exact angle needed for a shot.
As a quick refresher on an older rule, why do we say в бильярд using the accusative case?
In Russian, whenever you talk about playing a competitive game or a sport, you use the verb играть followed by the preposition в and the accusative case. This rule applies to everything from играть в теннис (to play tennis) to играть в шахматы (to play chess).
