    Don't have an answer, but I'll note 2 findings given the hint: 1) 505 is the hypotenuse of a triangle with integer length sides. 2) Rot13-ing the Roman Numerals for the number 105 produces a trigonometric term. Maybe one of these is on the right path and will help someone.

Here's one possible solution:







1. $505 = 1$ : Given

2. $DV = 1$ : By Romanizing left

3. $V = 1/D$

4. $CV = C/D$ : Multiply through by 100

5. $(PI)= C/D$ : By Rot(13)ing left

6. $Dπ = C$


By the circumference formula for a circle (C= πD),the left and right are equivalent




Q.E.D.

Reasoning




In Roman numerals 505 is DV. If we use rot13 on these two characters, we get QI.
Qi is the circulating life force whose existence and properties are the basis of much Chinese philosophy and medicine. It allows us to say that we are one with the universe. In this way, 505=1

By using




hexomino's idea of ROT13 on Roman numerals




we can obtain




$text{ROT13}(505)=text{ROT13}(V^4-V^3+V)=I^4-I^3+I=1$.

The rot13 translation of "one" is "bar". The only connection between "bar" and 505 that I could find is this very obscure definition given in urban dictionary (which was entry #4 and has more downvotes than upvotes), which says that it's slang for getting a drink at a bar with friends after work. Perhaps it's a really old outdated slang term, which is why your grandpa used it.

Elaborating on @hexomino answer 505 -> DV.




Is it possible that:




I want to DownVote you 505 times which was odd number resulting 1 DV.
var num=505; isOdd(num); function isOdd(num) { return num % 2;}

I'm not downvoting you.

    $begingroup$

    Working out possible solutions using rot13 and trig:



    I feel gross and like I'm doing something wrong doing this but:




    505 = 5 * 101 => V * CI




    Then you:




    rot13(V * CI) = I * PI => i * pi (getting pi honestly is the only reason I think this might be the right direction.




    Here's where the rot13(gevt) comes in I guess? Not sure where to proceed from there.

      If you use a "fivethousandfiftydecimal" base then 505 in this base is equal to 1 in decimal base.
      Just like 12 in octal base is equal to 10 in decimal base.

      Step 2 to 3 doesn't make sense, as Roman numerals are additive, not multiplicative.

      Reasoning




      In Roman numerals 505 is DV. If we use rot13 on these two characters, we get QI.
      Qi is the circulating life force whose existence and properties are the basis of much Chinese philosophy and medicine. It allows us to say that we are one with the universe. In this way, 505=1

      The rot13 translation of "one" is "bar". The only connection between "bar" and 505 that I could find is this very obscure definition given in urban dictionary (which was entry #4 and has more downvotes than upvotes), which says that it's slang for getting a drink at a bar with friends after work. Perhaps it's a really old outdated slang term, which is why your grandpa used it.

              Working out possible solutions using rot13 and trig:



              I feel gross and like I'm doing something wrong doing this but:




              505 = 5 * 101 => V * CI




              Then you:




              rot13(V * CI) = I * PI => i * pi (getting pi honestly is the only reason I think this might be the right direction.




              Here's where the rot13(gevt) comes in I guess? Not sure where to proceed from there.

                      If you use a "fivethousandfiftydecimal" base then 505 in this base is equal to 1 in decimal base.
                      Just like 12 in octal base is equal to 10 in decimal base.
