Factorial!

2 + 2++ = 5 in many compilers hahahaha

this one is too easy to try

Wrong hahaha, no increment or decrement operator, as this is not a mathematical operation, it's know only throw programming.

1. sqrt( (.2) ^ (-2) )
2. floor(sqrt(22))
3. fib((fib(2) + 2)!) = fib((1+2)!) = fib(3!) = fib(6) = 5
i would be interested to know if you have any more

Could you please send to me some links for old puzzles you have added, I want to try some of your puzzles and see if I can do any?
Puzzles like the "integers that their some less than 18, and I must know the product and the smallest no." will be great:->

This puzzle is for those who are aware of the "Mock Turtle"
This is the story of a squid called Sebastian, who ran out of ink. He called his friend, Archibald, who was an octopus, and asked him to buy some more Ink from the printers. So along went Archibald. "That will be 67 pence," said the shopkeeper, as he handed over the bottle of sea blue Ink. Archibald got out his wallet, counted out the money, and handed it over. But at the end of the day, when the printer counted up his change, he found he was short by 12 pence. "I've been robbed," he cried! A Mock Turtle from the local constabulary was called in, but entertained grave doubts as to whether Archibald really was a thief. "I was at school with the old fellow," he said, "and he never could get the hang of different branches of Arithmetic."
As everyone knows, the different branches of Arithmetic are Ambition, Distraction, Uglification and Derision.
But was the Mock Turtle right about Archibald? Or is his information just a red herring?
Editor's note: There are indeed some red herrings
* And yes Archibald is not a thief

An old Man has some savings X.
He has 7 sons.
When he divides the Money equally between two sons one dollar is left
If he divides between three sons equally then too one dollar note is left
Similarly if he divides it equally between four, five and six sons, one dollar is left.
BUT if he divides it between seven sons equally then nothing is left.
And the obvious question is, how much money he had in the savings ?
Not interested? Too easy? Then try this and weep.
Four guys are standing at the four points of a Square of length 1 mile (each side)
If they start to move towards each other at the same time.
how much distance they have to travel to meet, ofcourse what else?
WELL AND YES TOWARDS EACH OTHER MEANS
Guy 1 is moving towards Guy 2, Guy 2 toward guy 3, Guy 3 moving towards guy 4 and guy 4 towards guy 1 with a constant speed

puzzle of the day
This is a "simple" age problem
One evening in 1932 while sitting on the porch with my grandpa i suddenly remarked that
This year i was as old as the last two digits of my year of birth.
when i told this to my grandpa he astonished me by saying the same applied to him too.
Well that was one hell of a surprise for me...
pray say in 1932:
my age was:_________
implies my year of birth is:________
my grandpa's age was:_________
implies his year of birth was:__________
??? What confused thats why the name is "puzzle"

Can You Find
ROOT of a number on a standard calculator
WITHOUT touching the root sign or power sign a power sign also acts like a root sign
and believe me you can
Easy huh! try it ? tell me the EXACT steps
* Easy looking problems are sometimes the most challenging ones

I spent a while trying to figure this out - when you posted this on the Lounge. Could you post the solution here please?
Regards,
Nish
|
|
|
|

Hey Nish thats great,
you are a mathematician i always knew that
Here is the solution by using Bakhshali's Formula
sqrt(q) = sqrt(A^2 + b) = A + b/(2A) - (b/(2A))^2/[2(A + b/(2A))]
which comes down to
Sqrt(q) = sqrt(A^2 + b) = A + b/(2A) - (b/(2*A))*(b/(2*A)) / (2*(A + b/(2*A)))
sqrt(41)[^] = 6 + 5/(2*6) - ((5/(2*6))*(5/(2*6)))/(2*(6 + 5/(2*6)))[^]
Mathematical operations used = /, * , + , -
actually i posted the solution that day here[^]

Given a number, how do you pick values for A and b?
Say you need the square root for 308,197, now what would A and b be in this case?
Thanks.
Regards,
Nish

Hey Nish
only thing you need to do is divide the number into two parts
Q = (A^2 + b)
the only constraint here is
The Greater the A the better the Bakhshali Formula's result
So in this case if you take A = 550,
because A^2 = 30,2500 < 30,8197
so b = 308197 - 302500 = 5697
sqrt(308197)[^] =
550 + (5 697 / (2 * 550)) - (((5 697 / (2 * 550)) * (5 697 / (2 * 550))) / (2 * (550 + (5 697 / (2 * 550))))) [^]
This is accurate upto 5 decimal places
Even if you take
A = 500 , A ^ 2 = 25,0000 less than 30,8197
b = 58197
sqrt(308197)[^] = 500 + (58 197 / (2 * 500)) - (((58 197 / (2 * 500)) * (58 197 / (2 * 500))) / (2 * (500 + (58 197 / (2 * 500)))))[^]
This is accurate upto 2 decimal places
The Greater the A the better the Formula's result
So, it is simillar to the newton theory of approximation which is a iteration , but its one shot formula and gives much better result if A and b are properly chosen.
it was very recent that i also discovered about this formula and knew about Bakshali's manuscript you won't believe Bakshali's Manuscript were written on a Birch Bark and was found in a village in punjab (Bakshali is the name of the village) in 1881
i was totally amazed by the finding ,here[^] The manuscript is in oxford now
