9# Perform basic symbolic manipulation
10# For example, adding to the expression
11print(expr + 1)  # Output: x + 2*y + 1
12print(expr - x)  # Output: 2*y

14# Expand an algebraic expression
15expanded_expr = expand(x * expr)
16print(expanded_expr)  # Output: x**2 + 2*x*y

18# Factor the expanded expression
19from sympy import factor
