Ive just seen this puzzle on TGBBQ

Now ive had a few solutions

Heres one that ive thought of!

If you write the puzzle out as :

20 - 5 X 2 =
12 / 1 =
3 + 3 X 3 =

start off by adding all the numbers

so 20 + 5 + 2 + 12 + 1 + 3 + 3 + 3 = 49

Then the sums (without BODMAS)

20 - 5 X 2 = 30
12 / 1 = 12
3 + 3 X 3 = 18

thats 49 + 50 = 99

Or WITH BODMAS

20 - 5 X 2 = 10
12 / 1 = 12
3 + 3 X 3 = 12

Thats 49 + 34 = 83

What do you think?

How about 2649


Twenty-Five doubled = 2525
Twelve divided by one = 112
3+3*3 = 12
----------

2525
0112
0012
-------
2649


Samuk58, what country are you posting from

there was a rather rude post this morning in this thread [apparantly deleted] that suggested that this question was a hoax on a show aiming to attract more viewers/callers

I missed the post suggesting it was a hoax, it's one thing to attract more viewers but how much are they charging to phone in an answer?

The reason I asked Samuk58 where he was posting from was to determine the reliability of the contest.

So there may not be a correct answer to the riddle.

Another angle I was thinking about but not looked at yet was a letter/number transposition e.g., T=1, W=2, E=3 etc.

There are 10 different letters - T, W, E, N, Y, F, I, V, L and O.
Each a number between 0-9
Would I be correct in saying that's 9! or 362880 combinations?

Well now.

According to : http://www.mathsisfun.com/operation-order-bodmas.html it's

BODMAS !

B Brackets first

O Orders (ie Powers and Square Roots, etc.)

DM Division and Multiplication (left-to-right)

AS Addition and Subtraction (left-to-right)

The only strange name is "Orders". "Powers" would have been a better word, but who could remember "BPDMAS" ... ? "Exponents" is used in Canada, and so you might prefer "BEDMAS", there is also "Indices" so that makes it "BIDMAS".

In the US they say "Parenthesis" instead of Brackets, so they say "PEMDAS"

I'm from the USA and learned the following definitions. What do you call the [] characters?

Code: Select all

()   Parentheses
[]   Brackets
{}   Braces

In Britain they are all called brackets. That is :

Code: Select all

()   Brackets   
[]   Square Brackets
{}   Curly Brackets

That is so in an informal context. In careful speech or typographical circles practice is identical to that of the USA.

This ancient graffito rhymes:

What manner of man is this

Noticing an item in a daily paper about ITV's The Mint quiz program moving to ITV2 or 3, I came to realise the 'The Mint' is being shown in the UK (rereading these posts I notice there was a slight clue in Samuk58's 2nd post).

Here's a link to the rules. No mention of the riddle here.

My basic math skills appear to be failing me today, along with my spelling.

Samuk58 claimed to have attempted all the obvious solutions, which I believe to include both 3+(3x3) and (3+3)x3 in his sums.
This would imply that the number Twenty-Five is not simply 25 doubled but rather Twenty-Five less Five to equal 15 doubled, as claimed by Harvard.

with 54 being the response.
