Oooohh .. a PUZZLE !

(6*6+6)/6 = 7  ...no

(6+6)/6 + 6 = 8  ...no

### Re: Hi?

I tried dozens of combinations and none of them work ... it may be impossible to do following those instructions!

### Re: Hi?

(6 + 6) \ 6 + 6 = 8
(6 - 6) x 6 + 6 = 12
((6*6) +6)/6 = 7
(6+6+6)/6 = 3
(6*(6+6) / 6 = 12

Going on, etc. It'll not work. The Maths is right.

### Re: Hi?

i hve too tried a dozen of combinations and i kept trying for 2 hrs. its not working!
i dont think its a correct ques! better check it again and then tell us. if this is d ques then it is impossible to do.
FOR SURE!

### Re: Hi?

I think that's impossible, because straight off I realised that you are only working with numbers in the 6 times table, no matter what you do. Is nine one of them?

### Re: Hi?

9's not in the 6 times table. Numpty. But, if there were 5 6's, I expect I could get it to work...
(6+6+6/6) +6 - That's for 5 of them, but, bleh.

### Re: Hi?

Well, we had fun trying. But this one is headed for the circular file.

I hope random_blonde can tell us what her teacher reckons the answer is.

Probably involves standing a 6 on its head

Nothing is really impossible in life but in maths that is the hard thing about their is only one answer and quite a lot of things are impossible in MATHS!!!!!!!!!!!

### Re: Hi?

Interesting point, Ceno.

Yes, things can be impossible in maths when we set limits, such as how do you make 3 using 1 and 1.

But on the other hand, maths can reach outside our universe by happily dealing with multiple dimensions, infinite speed and things like that.

### Re: Hi?

But how do you know, Mr T?

An electrical engineer was able to use "imaginary numbers" to prove that a seemingly normal circuit would in fact blow up. Noone believed him because it wasn't real. They connected up the circuit, and *foop*. THEN they believed him. Maths had seen outside the normal experience.

(An "imaginary numbers" is based on the square root of -1. What is the square root of -1?)

"Math Error"

But, "imaginary numbers" are defined as 'J'

or even 'i'

Why did the vector cross the road?
It wanted to be normal.

Yes, that is what is so interesting. Maths goes beyond what we think is real, and shows us a reality far exceeding our normal experience. Every so often this new reality shows us a new thing about our normal life.

### Re: Hi?

The "i"s have it

Yes, the classic way to show an "imaginary number" is to use an i (or sometimes a j).

So, 4i is 4 times the square root of -1

And a "Complex Number" is one that includes "Real" and "Imaginary" numbers. So, for example 2 + 3i is a complex number.
