Question 1194925
.


Question 2 is mathematically non-sensical.


Question 3 is mathematically non-sensical and is written in illiterate way.



Having two questions in the post, written in illiterate way,

I do not find possible for myself to answer third question.



If in the future I will see similar posts, written in illiterate way,

I will collect the links to these posts and will write to the managers

of this project asking them to REMOVE from the project those who submit this nonsense.
