ramey_steven Here is my stab at the logic, derived from giyam's answers below and Googling set notation:
Give me the set of x such that for all y in set(x) and set(y) is a function of (where) y <= x
However, I think the italicized section above is unclear due to the nature of the problem as it is written...that is, what is the relationship with y and 'S(x)' after ∀?
Definitions:
∀ = forall (https://en.wikipedia.org/wiki/Turned_A)
| = such that (https://en.wikipedia.org/wiki/Set-builder_notation)
∧ = logical conjunction (and)(https://en.wikipedia.org/wiki/List_of_logic_symbols)
→ = is a function from(https://math.stackexchange.com/questions/1740154/different-arrows-in-set-theory-rightarrow-and-mapsto)
jackliusr find a specific x in set S which all numbers y in S are less or equal to x.
generalbaguette That's super weird notation. Why not use , also there should probably a colon or dot or space after the .
shubham_mahawar Not understand the question properly It looks like find x from s(x) and y from s(y) and check y<=x
then there are many possible combination of this as 3<=3,4,5,6,7,10,11,19,18 4<=4,5,6,7,10,11,19,18 5<=5,6,7,10,11,19,18 6<=6,7,10,11,19,18 7<=7,10,11,19,18 10<=10,11,19,18 11<=11,19,18 18<=18,19 19<=19
total 45 but it is wrong anyone explain plz
matt_irby I'm going to take my stab at rephrasing the formula as it tripped me up to.
It's asking to find an x in S such that any y in S means y <= x.
So, it's asking which element in S is greater than or equal to any other element in S, including itself? This would be 19 because it is the greatest element in the set, therefore it is greater than or equal to all the other elements in the set.
imtiazu8 what is basically x and y here, so that y<=x?
sai_jeelakarra the answer is 19 beczz the maximum value of x for any y<=x in s is 19
yashtrivedi7_yt It is basically asking to find out the largest number in the set for x so x may be equal to y or greater than it I still havent deciphered the exact statement in terms of words like x or y in the sample space x...
Please if anyone give me the exact relational statement and don't point to wiki pages as i have spent a lot of time researching this and haven't found the exact answer
amitrapstar CAN ANYBODY EXPLAIN ME THE RELATION PLEASE.
yogesh_suthar x such that for every y where S(x) means x belongs to S and S(y) means y belongs to S implies y <= x is true

shivu_narang can you help me to get answer? I didnt understand
Adil_MuthukoyaAsked to answer Its actually finding the biggest number in the set , that is you have to find the value of X such that for every Y, X must be greater than or equal. in all (X,Y) pairs
shivu_narang can you help me out? I am not able to do it.... please give me an example to do this
Adil_Muthukoya its about understanding the expression in the question . https://en.wikipedia.org/wiki/Boolean_algebra this link may help you
giaym give me x, that belongs to S, that is greater than y, that belongs to S, for every value of y
is that reading correct? never done this
Soniabhishek36 can you please explain it here ?
giaym a) x| -> give me x
b) Vy -> for all possible values of y //missing a comma or something to separate from the rest, i got lost reading that
c) S(x) -> x is part of the set S (x values come from S)
d) ^ -> and
e) S(y) -> y is part of the set S (y values come from S)
f) -> -> such as, just another condition
g) y <= x -> y is <= x
so you grab a value of x from S (c), and check (f,g) against every y value from S (b,d,e), if it passes, then success (a)
mainak_bhadra very good explanation. it helped me solve the problem. Thank you
