Digits 2, 4 and 5 are correct, your answer only contains one prime number.

I forgot 1 wasn't a prime number due to the language of the stupid rule :oops:

Don't feel so bad. I forgot that the number "2" WAS a prime number. :oops:

I'm sorry for the confusion, I type them as they are in my puzzle book.

Puzzle 15

Complete this grid with the numbers 1 to 6 to make the sum correct.

Each number is only used once.

There is no ÷ 1, and at no point is a decimal or fraction used.

_ + _ - _ × _ ÷ _ × _ = 50

This took me a while to work out:

It would have to be 4 add 2 - 1 x 6 divided by 3 x 5. That must be the only logical solution?

After looking at the question and realizing it's impossible I looked up the answer on the internet. What wilki has is what the internet states, but if you do the math it is incorrect. Wilki's anwwer actually equals -4

4 + 2 - 1 x 6 ÷ 3 x 5

First you add the stuff not attached to multipliers/dividers
(2 + 4) - (1 × 6) ÷ 3 × 5 which equals 6 - 1 × 6 ÷ 3 × 5

Then you multiply/divide left to right
6 - 1 × 6 ÷ 3 × 5 which equals 6 - 6 ÷ 3 x 5

Again multiply/divide left to right
6 - 6 ÷ 3 × 5 which equals 6 - 2 × 5

One more time
6 - 2 × 5 which equals 6 - 10

Finally you have
6 - 10 = -4

Yes, I know what you mean. BIDMAS is what they tell us at school: brackets, indices, division, multiplication, addition, subtraction. I was going by the theory that you need to work from left to right. However, technically dire wolf is right, although I think the answer I've got is likely to be listed as the correct answer. I'm happy to forfeit the point if it is listed as the correct answer because it technically isn't. Unless I'm completely wrong in which case disregard this post.

Your answer is correct according to the internet, actually it was 2 + 4 but that's irrelevant. In the example I found it stated "work left to right" which is what you did. Looks like we may both be right

I don't think that sum can work with BIDMAS, so I believe Wilki is right.

The answer listed is what wilki has put, however, since direwolf's answer makes sense I think I will give half points to both of you if that's alright with you two?

I say just give the point to Wilki. Wilki's answer is actually an answer. I answered nothing

In the UK, maths exams always give extra marks for working out so I think direwolf deserves half a point.
