"fun" little problem
Our tutor gave us this in the tue and it's driving me insane
you have 4 numbers 1 3 4 6 you have to use only multiplication division additon subtraction and all the numbers and get 24 Someone do it for me, so that I can die happy

Do you have to use
multiplication division additon subtraction As in have to use all of them? and each number only once right?? first thing for problems like that. Look for loop holes.

no you just can use
multiplication division additon subtraction but you have to use each number once it woudl be easy if you could use them multiple times, or not at all

Next question, can i arrange them to form new numbers?

It doesn't, it's merely a way to write down the multiplication...

Ah, you mean 'five to the second power'...

#10




ack
yeah it either uses a 2 or a number twice there are two ways to write it but still you are wrong

I don't care what you say, I feel smart for at least coming up with a way

What were the extact instructions? Did them mention anything about prime numbers? If you don't have to use primes, the answer becomes 6*4=24 since 1 and 3 are primes.

I don't see why you are dismissing the primes, we have to use all four numbers
There was no mention of a special case for primes

solved it
3*6 = 18 +1 = 19 +5 = 24 no tricks involved

That's good except where'd you get the "5" from?
The numbers in the problem are 1346. 
#17




hmmm
I don't know I don't even know if the original number was a 4 or 5 I'll get back you next wednesday on whether it should have been a five or a four

Let me guess, your three was the key to solving the problem since "Three is a magic number!"
"Hey Rocky, watch me pull a five out of my hat. Presto! Whoa! I better get me a new hat."

well... TECHNICALLY, using rounding, 6*4+1/3=24
as 1/3 = .333333 which is less than .5 Ok, so it's a bit cheesy, but is technically correct. Otherwise, I can get almost any number BUT 24 
#20




Technically correct my ass... Rounding numbers to integers isn't default practice. Otherwise I'd fill my car's fuel tank by dripping the fuel into it: How much does one drop of fuel cost?

LeeCheSSS  Actually, there IS rounding happening at the gas tank, it's just to the nearest 1/1000th (at least, here in the states it is), and to the nearest penny.
Rounding happens everywhere  there are just generally accepted digits that rounding happens at. For instance, State Sales tax in California is 8.25%  This doesn't make for "whole penny" numbers  which means that rounding must happen. This is part of what Arthur Anderson is in big trouble over  each of those fractions of cents were being diverted to various accounts. When dealing with millions of transactions a day, 1/10th of a penny adds up VERY quickly! 
#22




Any word yet weither it was meant to be a 4 or a 5?
