equalto /greater than OR greater than /equal to Contextually I understand why it's (0,infinity) but > w/ dash under as 2 means aka till it and till it or infinity x≤1/2 can mean (0,1/2) or (1/2,infinity)

@Genady thanks

@studiot In Symmetric difference why is intersection of 3 not included, also what its associative. Symmetric difference means "unique to" ? So AΔBΔC != (AΔB)ΔC

So conclusion is null set is a subset of everyset ands ∅ is not always a element of every set.

@Genady De Morgan's Law I think this is false when C⊂B with elements of A U B

@Genady Explain this doesn't makes sense to me. This implies if x doesnt belong to intersection of 3 sets that means it doesn't blong to any set.

@Genady I am having problem understanding these

This doesn't makes senseIf x e (A1 n A2 n 143 n ... ) then x is not the element of at least one of the sets. This implies if x doesnt belong to intersection of 3 sets that means it doesn't blong to any set. De Morgan's LawI think this is false when C⊂B with elements of A U B If A A B = A A C, then B similar to Symmetric difference with 3 setsIn Symmetric difference why is intersection of 3 not included, also what its associative. Symmetric difference means "unique to" ? So AΔBΔC != (AΔB)ΔC Cardinal Number of set Union of 4 SetsI thinkg it should be - n(AUBUCUD) = [Sum of number of elements in sets A, B, C and D] - [Sum of number of elements of intersection of sets taken 2 at a time] - [Sum of no. of elements of intersection of sets taken 3 at a time] - Elements of intersection of all sets

It breaks the rule number of elements of a powerset of Set A = 2^n . Also contradicts null set is a subset of everyset. Also some places it says ∅ is a element of every set 2^4 = 16, but my results say 39 Example for set {1,2,3,4} There can be 5 no. of sets n+1 single element = n 2 element = 10 - {1,2} {1,3} {1,4} {2,3} {2,4} {3,4} {1,∅} {2,∅} (3,∅) (4,∅) 3 elements = 10 4 elemets = 4 =>{1,2,3,4} {1,2,3,∅} {1,2,∅,4} {1,∅,3,4} {∅,2,3,4} 5 element = 5 additional the ∅

@genady i don't understand please help

1 mol m–3 = 1000(L/m3) × molarity (mol/L) The 2nd equation seems to contradict the definetion, how is it using both cm and m in a forumal, i am having trouble understabding the conversion factor

What I do I give it pdfs and a long instruction, and then ask questions. Best Service and Local LLMI use ChatGPT, should I switch to something else or something local ? Give AI access to screen, able Point-&-Ask while reading ? I saw video people doing similar things w/ Gemini, Claude. 1. I may use local OCR/CV and send it to LLM as text. 2. and use local Speech to text ? Should I give ChatGPT access to local files for this purposeLangChain - TechLinked - https://www.youtube.com/watch?v=9AXP7tCI9PI Local LLM Retraining, RAG, Context Docs - https://www.youtube.com/watch?v=fFgyOucIFuk How else can I use AI to study ?

xA is xA/xA+XB as the question is asking liquid ratio so LiqA/LiqA+LiqB

@KJW I don't get the context of "The number of moles is inversely proportional to the molar mass." in van't hoff's factor. The definition/formula in book seems self-contradictory.
