Trevor, it seems you need easier ones A is the incorrect answer, and didn’t you learn in school that you suppose to put your workings into your answer to get full marks

Chris well done, your formula is slightly different to our solution, but you managed to come out with the right answer!

@TREV – Mate, this was a hard one, one which I reckon 90% of people wouldn’t be able to solve. That said, based on your answer, I think we’ve got hard enough

To be honest, this took at least 15 minutes and involved a pen and paper, dare I admit!

The difference between
the top and bottom values on the left, plus the difference between
the top and bottom values on the right, equals the middle value

Visually:(top left – bottom left) + (top right – bottom right)= centre

So there is a reversal of the + and – signs, which would still produce the same result.

I’m amazed that there are two approaches to solving this! Makes for an interesting thought that if the adjacent sides can be calculated like this, one would imagine the sets to be symmetrical of sorts, in a 3D manner?!

I was also surprised to learn that it could be solved through two different sums, just shows you that there is more than one way to skin a cat! Nice puzzle, not an easy one for me!

I tried the diagonal method on the first image but did not come up with the same centre value (F), so face it Trevor you have been voted off as the weakest link. Sorry

A ;-)need harder ones

Wait foooooor it, G.

Calculated by the difference between the sum of the top letters and the sum of the bottom letters in each set.

Visually: (top left + top right) – (bottom left + bottom right) = center

Kerry – I’m curious, what was your formula?

Ok Chris, here it is

The difference between

the top and bottom values on the left, plus the difference between

the top and bottom values on the right, equals the middle value

Visually:(top left – bottom left) + (top right – bottom right)= centre

So there is a reversal of the + and – signs, which would still produce the same result.

Wow, deep bru!:)

Haha! Perhaps a little too early for this conversation

Speaking of dimensions Chris, I came across the following animation, quite interesting, I think I got lost around the 5th dimension, but good to know

That’s an awesome video Kerry!

I think this is the limit of difficulty, it’s too hectic trying to solve these after a long day of work or during the day! haha

a number of answers could be right, what happens if you did the diagional numbers….thats what i did

I tried the diagonal method on the first image but did not come up with the same centre value (F), so face it Trevor you have been voted off as the weakest link. Sorry

OMW, ahhahahahahahaha!

What did I win?

You have won your dignity back Chris. You made up for all the losses on the lateral thinking word games!

I must admit Trevor you were quite sharp in this department, there is hope for you yet

Oh C’mon, those word games are too boring, not enough logic involved

Now now children!

Boooooooring! Gimme Numbers!

Ps. Watch out, Editor’s going to moderate us!

It’s all about balance (left

andright brain)!Oh you are so going to need that scientific calculator next week….hope you still remember your cosine, sine and tangent functions, hee heee heeeeee!
