Why Variable is always taken as positive?
I think all of you have question why we use x as variable not "-x"?
So after researching all night I found the answer, so here it is.
So after researching all night I found the answer, so here it is.
If we take +ve sign with variable we find real sign of the answer l.
For e.g.
+(+ve)=+ve
+(-ve)=-ve
Here if sign of x is negative -ve then answers sign or operation us changed.
If we use - sign then we gave to reverse the sign of answer also.
For e.g.
2+__ =3
1. If value be x then
2+x=3,
x=1
2. If value is -x
2-x=3
x=-1.
HOPE ALL OF YOU HAVE UNDERSTOOD IF HAVE ANY DOUBT TELL IN COMMENT SECTION.
