Re: Get 24 from 1, 3, 4 and 6

Hmm, what about the same problem but with numbers 8,6,7,5,3,0,9?

Re: Get 24 from 1, 3, 4 and 6

My guess is that such a solution is not possible if we are limited to +, -, /, * operations. I don't know enough Maths to prove or disprove this. As a newcomer to programming, I tried to have a crack at this in Python. I found 23, 23.(6), 24.(3), 25 but no 24.

Re: Get 24 from 1, 3, 4 and 6

I couldn't figure it out, I am sure it involves some clever use of distributivity... At first, I decided to factor 24 into prime factors 2*2*2*3 = a*a*a*b = (a^3)*b (note in this case (a^3)*b = 2*(a^2)*b = (a^2 + a^2)*b Listing out the numbers we have: 1 = e (multiplicative identity) 3 = b 4 = 2*2 =...

Re: Optimal solution please

Are we all agreed the answer is e? (pi wasn’t an option.) It made sense to me. In each of the columns the middle square represents the union of both the upper and lower squares of that column less the common elements they share. For the unknown square, look at the first square in that column and lo...

Re: Silly questions

Would calculating the variance of the variance of a data set ever be useful? I can't figure out if this statistic would convey anything new?

Ricky Jay, phenomenal magician.

RIP
Truly amazed having watched a couple of videos on Youtube, how did I not come across this individual before? His diction alone is a reason worth watching him perform. RIP, indeed.

Re: Is the type of mathematics found in finance limited?

The question I have is this: Having only possess a very limited background in maths, should I then strive to learn the 'limited' maths of finance well (which is no easy feat in itself) or should one learn as much maths as one can outside of the 'limited' scope of finance and continuously think of a...
