# Exercise: Combining Operations
#
# Multiple arithmetic operations chain naturally.
# Each operation consumes its inputs and produces output
# for the next operation.
#
# Examples:
#   2 3 i.+ 4 i.*    # (2+3)*4 i.= 20  (explicit operators)
#   2 3 + 4 *        # (2+3)*4 i.= 20  (inferred operators)
#   Stack: ( 5 ) after +, then ( 20 ) after *
#
# Your task: Calculate (10 + 5) * 2 to get 30.
# When done, delete the marker line below.

# I AM NOT DONE
