Some Equations
As an educator, I have always enjoyed creating my own puzzles. This makes it so people cannot just look up answers online. They either solve it or will never know the answer. Enjoy this puzzle. I would call this "extreme" in terms of difficulty. Good luck!
I have invented a mathematical system. I can always give you more information about my mathematical system, but this should be enough for you to dig in and figure things out!
I. 10 + 110 = 120
II. 1 + 1 = 10
III. 211 * 10 = 1100
IV. 4020 / 1001 = 20
V. 121,310 - 112,220 = 4020
VI. 43,011 - 24,301 = 13,110
Using these equations, solve the following problem:
Let A = 1. Let B = A + 1. Let C = B + 1, and so forth.
What is ABCDEFGHIJK - 1?
Hint: I used Roman numerals just to differentiate from my math system. They are not part of the problem.
I was so happy to have figured it out, thinking it was 10,000,000,000.
Then I looked at the comment thread, saw your answer, and went: "Now how did you get to that answer?"
Then I saw Dimby's response and was even more confused.
Then I went back up and re-read the question. Oh. Yeah. A..K minus one. Oops!
My first impression was that V and IV as well as I and II or I and III are directly connected; there's no need to solve the pattern. This doesn't seem to hold, though. Also, bases don't seem to work here (ABCDEFGHIJK is 37713647386641440 from base 36), so I'm stumped so far.
i dont think its a kal alt all kal does is comeback every few months and see that the site still wont let him write whatever and leaves. also izna is too developed (65 levels!) to be an alt
