Math quiz

You almost got me to do your math homework. Well played jazzc. Well played.

My BSc is in Applied Mathematics, I can do my own homework if I ever have to, thanks :o
 
I've got 0 for a and 4 for b.

Correct. Think why it 's 4 and how we can get the answer is for 1 billion lockers/people and send me the explanation via PM :)
 
300000000

Your post count does not increase in the lounge :) (and you get banned if you try to inflate your post count without actually taking part in discussions btw)
 
I got the easy question:0

For the difficult question.... couldn't finish it because I ran out of lockers:frusty:

Thanks everyone for taking part so far, keep the submissions coming!
 
Really fun brainteaser!
Everyone who's trying the second one - look at the numbers of the lockers which are left open for, say 10 lockers.
What stands out about those numbers? ;)

@jazzc: I'll PM you another fun one ;)
 
Have you got the formula to calculate the total of opened lockers?
 
One more person added to the winners list! :)
 
And yet another one added! :)
 
math... giving nightmares to people like me. not my thing. adding, subtracting, multiplying and division are doable... using calc :)
 
One more member added to the winners list! :)
 
Have the answers been posted in the thread? If not I'll give it a go when I wake up.

Need to get my brain working as unfortunately I need to learn math or else I will fail college. lol
