Re: Problem
Are we allowed to add, subtract, multiply and divide?

Re: Problem
yes you can use the main signs add subtract multiply, divide not to sure weather too treat it as a logic problem?

Re: Problem
((8 / 3) x 8 )+3=
= (2.6x8)+3
= 21.3 +3
=24.3 when u round it
≈24
or
((8x8)/3)+3=
=(64/3)+3
=21.3+3
=24.3 when u round it
≈24

Re: Problem
Well, that would work, YiAnZ, if we are allowed to do rounding.
Are we, Steve123? And were you giving us a clue by saying it might be a logic problem? Is there a trick here?
I can get (8-3)*3+8 = 23 ...
And with an extra 3 I can get (3+3)*8/3+8=24
With some logic I could ignore a 3 and 8, and just use 3*8=24

I am getting the feeling this one can't be solved.

Re: Problem
I think it's the 24 game. Has anyone heard of it?

Re: Problem
Rora has got it right, y'know. That's the logical answer.
Boy let me tell you what:
I bet you didn't know it, but I'm a fiddle player too.
And if you'd care to take a dare, I'll make a bet with you.

Re: Problem
Are you allowed to join the numbers together...as in 33 or 833?
And what level is this problem for? What symbols or functions would be known?

Re: Problem
The guys who posed it said "yes you can use the main signs add subtract multiply, divide not to sure weather too treat it as a logic problem?"
It seems to me that "Logic Problem" is a clue. It may not be solvable, I don't know.
