Why is the expression written this way?

Question

Informatics

For example I have:
x=1
I need to add one to it.
Why do they write:
x=x+1
and not just:
x+1
or even like this:
x=2;

Answer 1

In algebra, the notation x=x+1 denotes an equation to be solved for x, moreover, with an empty set of solutions.
Are you confusing algebra with programming?

Answer 2

This is not an algebraic expression, but an assignment operation.
I recommend opening a computer science textbook for the 5th grade. They are just studying it
