About variables and equations

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
