Not all X are Y. Is this translated as X some (not)Y? Also, is Not all X are Y equivalent to X some Y? For the latter question, I know in English in certain contexts, the statement "not all" of something implies "some are."
So, quick question. What's the best way to improve on translating from English to formal logic? Just redoing the drills already in the curriculum? Any other supplemental material anyone recommend???
After BR, should I watch still watch the explanation videos of the 1. non-circled questions I got correct with 100% confidence and the ones I circled and got right with no answer change? Thank you!
