Why is my variable not updating with an its answer?
For Example:
If write a= 6;
A=a^2;
A
I get 36 which is right.
Now if I give a=5;
A
I still get 36!
Should not the value of A be 25?
Should I re write A=a^2; before giving A after updating the value of a?

Hello shreekanteshwara,
so your workflow is->
a=6;
A=a^2;
now the value of 'A' would be 36
Now you updated a to 5
a=5;
Value inside 'a' is 5
but the value of 'A' would still be 36 because you have updated 'a' only not 'A'
if you want value of A to be 25 then you have to rewrite the statement A=a^2
so the answer to your question-->
Should I re write A=a^2; before giving A after updating the value of a?
-->Yes you have to rewrite
