In mathematics: * The symbol **x** usually represents an **unknown** quantity or **variable** quantity. Example: ( 2x + 3 = 7 ) So here, **x** has no fixed value until you solve for it. --- In computer science / programming: When you write something like: ```c int x; ``` it means: *...

@Evo The problems is my english is not that good , that is why the errors in the usage . Yes i actually meant "questions" itself . Thanks for correcting it

OK , i understand at least half of it Thanks a lot for the detailed explanations :smile:

Thank you for answering my strange questions . I found this book called , homework helpers basic math and pre algebra and i feel like refreshing and improving my basic maths . This book is a really good book to refresh maths . One of the best books i have read . I have to start with numbers...

I have this one more question , If x is an unknown quantity that makes up the equation , find x Isn't that also correct ?

@ symbolipoint Thanks a lot for your reply I am not that confused now :)

@ jbriggs444 OK , i think i understand Thanks a lot for all those examples

@ jbriggs444 Thanks for the reply . In computer science , it looks like this from my notes ... This is a declaration. Declare an Integer line called x int x; This is an initialization. Initialize Integer line called x int x = 0; For mathematics i wrote it down like this in my notes...

@ fresh_42 I was also trying to prepare for a government test and it has lot of mathematics and quantitative aptitude tests . So all these things came to my mind , so i thought i would ask here I will ask here if i have more doubts Thanks for the all the important points .

@ fresh_42 After trying to learn some computer programming i lost some basic concepts of both mathematics and computer science Thanks a lot for all those explanations .

So the unknown variable name X can either be fixed or it varies depending on the equation ? i think that is why i was trying to narrow it down like this , "x" as an unknown object that is fixed or varies ? Is that more correct ?

So X denotes an unknown something , and that's it ? Is this letter X called a variable name of an unknown something ?

Can i call "x" an unknown object that varies ?

other than "hello world" ? nothing this is in our syllabus ..which is why i think i am going to loose my degree
