Here is a math problem which I had a midnight crisis about.
IF
5+3+2 = 151022

9+2+4 = 183652

8+6+3 = 482466

5+4+5 = 202541

7+2+5 =

Spoiler (show)

144547

(Ron2k Provided A solution)

Think I see what the pattern is:

For (a + b + c):

The first two digits of the solution is the result of (a*b). Let this result be x.
The second two digits of the solution is the result of (a * c). Let this result be y.
The final two digits of the solution is the result of (x + y - b).

Based on that, your solution for 7+2+5 should be 143547.

Thanks I show what I did wrong the first time, It was not that complicated thou.

Sorry about the thread rename as well, you just posted after I saw the pattern emerge.

Rather create new threads for new topics - otherwise it just confuses everyone else.

Sorry, All logical thought starts to leave one for every minute past midnight. This was a mighty long day, I think it time to plan a vacation.

Tell you what - try and restore the original post for this thread, then create a new one for the vacation stuff. That would probably work best.

And also, it means that I can sleep easier knowing that I won't wake up to a private message inbox overflowing with "OMGWTFHAX" messages from confused forumites, or be woken up prematurely by even more confused phone calls from Anakha56. (Yes, this has happened before.)

Okay Restoring old thread.

That is the last thing I would want to happen.

So you want to visit Durbz but dont like the heat? In December? I r confuzzled... Maybe I should phone the iRon...

What requirements are for your holiday? Beach or mountains? Beach will probably be better and I would suggest Ballito...

It is not the heat so much a the humidity the beach is a fine choice for a week and no longer, We were(that is the people going with me and I was vote as the manager of the trip, one night like this one) thinking and going somewhere after that week(ran out of ideas).

I ran into another one:
If
5+3+2 = 13071015
9+2+4 = 14343336
8+6+2 = 46104048
Then
7+2+5 =

// boy but you lot get up to mischief in the dead of night....
// and what's this about Anky phoning Ron early mornings.... is there something we don't know... not even I dare to phone the Lurker that early....

ok.

a + b + c = w x y z
(w, x, y & z are all 2 digit numbers)

w = (a) (b) - c
x = (a) (c) - b
y = x + x - (a + b + c)
z = [(a) (b) (c)]/2

Therefore:
7+2+5 = 09130835

I know I am fussy but shouldn't 7+2+5 = be written 7 & 2 & 5 ? + to me means add not and.

w = (a) (b) - c
x = (a) (c) - b
y = x + x - (a + b + c)
z = [(a) (b) (c)]/2

Therefore:
7+2+5 = 09130835

That is the correct solution. Very Good

There is no need the + is there to confuse the the cryptographer.

Tribs, just look at it like this:

f(a+b+c) (meaning that a+b+c goes through a procedure that gives those weird answers)

That makes more sense Monty.

I was able to answer the first set easily - but this second gave me a modicum of trouble. I got the w, x, y but the z really confused me. Well done.

Here is another one.
If
7 + 1 + 8 + 5 + 4 + 3 + 6 + 2 + 9= 23987793
Then
4 + 9 + 7 =
