On the Subject of Reverse Polish Notation

coding trauma.

Final Answer: Take absolute value, then mod 1,000,000, round off to 3 decimal places.

NOTE: For division by 0, take the answer to be 0.

Replace letters with numbers:

If a letter returns 0, change it to 1. (#// = Number of parallel ports)

A	#batt × #modules (EXCLUDE needies)
B	(#ports - #indicators) ^ 2
C	(#battholders + 2) ÷ SN last # (Answer: drop remainders)
D	Sum of non-encoded numbers + 10
E	(#serials + #//) ? SN 3rd character Multiply if Stage 1/3; Add if Stage 2
F	[(#portplates + #ps2 + #rj) mod 9]-th Triangle #
G	#solvable modules LUNAR ADD #original minutes round down #original minutes to nearest integer EXCLUDE needies

Reverse Polish Notation (example):

3 5 + 7 2 - * postfix notation (RPN)

• 3 5: (3, 5)
• +: (3+5) = (8)
• 7 2: (8, 7, 2)
• -: (8, 7-2) = (8, 5)
• *: (8*5) = (40) <-- answer

Lunar addition:

Take the largest digit in each position.

• 726 + 351 = 756

Triangle numbers:

n-th Triangle # = 1 + 2 + ... + n = n(n+1)/2
