puzzle giveaway, closed, solution added

7 solvers, 2 entries by now; updated

Math is not supposed to be easy :)

it can be done with school math, pen, paper and a scientific calculator

ok, grats on solution of first part

if no one gets both, i split the puzzle, so every one who gets one can enter :)

i'll check it again....

you're right, i forgot to divide by sqrt(5)

use the updated link

borisu solved it and i double-cheked, corrected the error in the second one, so everything should be fine now ;)

since i am a computer scientist, i did choose appropriate numbers to prevent solutions by simple programs ;)

do not try to calculate the 12345678901234567890th fibonacci number unless you have the ~500 petabytes of memory to store it ;) - you only need the first 10 digits for the solution ;)

the first part can be done with pure paper+pencil - or with the computer

i set the ga to 4 weeks, so you have plenty of time :)

its a division scheme, just as you lear in school in 3rd grade or so. going down you have subtractions.
i just saw, the "long division" is a bit different.
just compare wikipedia articles german and english to get the right notation

ill give an example:

5043:41=123

41

--

94

82

--

123

123

no rules about repeating digits.
there are no leading 0s.

such great things as fibonacci numbers are from heaven, not hell ;)

i considered 1 to be the easier one

then you lied at Q3 ;)

Can't say if really too hard, didn't start solving yet - not enough free time (good it's 3 weeks long, as it is nice puzzle). After quick glance, it looks that with hints shouldn't be that hard (I didn't know there are different notations for Q1). I'll definitely give it a go - i like math :)

jup...about 500 petabytes of memory just to store it ;) - but you only need the first 10 digits, so forget about the rest of the numbers and do a good approximation ;)

did you use the correct format? 1234567:123=123456

sure you got the correct solution?

first hint of Q2:

try not to calculate the actual fibonacci number (you would need about 500 petabytes of memory just to store it / more than all paper on the world to write it down)

since i am a computer scientist, i did choose the numbers to prevent such solution attemts ;)

thx :)
