One day, the police found a man dead inside a hut. In his left hand, he's holding a gun. In his right hand, he has a recording. When the recording is played, the police hear the men talking about how horrible life is and how he wants it to end. The recording ends with a gunshot. The police are about to call it a suicide until you point out a very important clue. What is it?

When the celebrated mathematician Karl Fredrich Gauss (1777-1855) was nine he was asked to add all the integers from 1 through 100. He quickly added 1 to 100, 2 to 99, and so on for 50 pairs of numbers each adding to 101. The answer was 50*101= 5050. Now find the sum of all the digits in integers from 1 through 1 000 000 000. That's all the digits in all the numbers, not all the numbers themselves.
The numbers can be grouped by pairs.
999 999 999 and 0
999 999 998 and 1
999 999 997 and 2
and so on....
There are half a billion pairs, and sum of the digits in each pair is 82. The digits in the unpaired number, 1 000 000 000, add to 1. Then: (500 000 000 * 81) + 1 = 40 500 000 001
You and your friend are trapped in a space prison on an alien planet. The alien warden decides to give you and your friend chance at freedom. He states that your friend shall be allowed to temporarily leave the cell and try to escape through an electric gate guarded by a 3-digit pass-code. If your friend answers incorrectly or says anything but the final answer, your friend will be thrown back in the prison. A computer will tell your friend 4 clues if requested. If this pass-code is properly answered, you and your friend shall be freed. You are then blind-folded and your friend leaves. You hear your friend walk down one of the numbered halls to the gate. Your friend asks for the first clue. A voice answers, "The numbers are in ascending order so that the number is greater than or equal to the number before it." Your friend asks for the second clue. The voice says, "the product of the 3 numbers is 36." Your friend asks for the third clue. The voice says, "The sum of the numbers is the number of the hallway you entered." Your friend passes for a moment and thinks. Your friend then asks for the fourth and final clue. The voice says, "The largest number only appears once in the code." You hear a beep, and you are free. What was the code?

While playing with a metal washer shaped like ring. Dave accidentally pushed it on his finger too far and couldn't get it off. He tried to remove it using soap and water, it didn't work.

Just then Bob arrived on the scene and suggested an easy way to remove the washer in just a few minutes. What was the solution?
Bob suggested that Dave hold his finger in the air while someone around a piece of tightly around just above the metal ring. The string forced the swelling down. As they unwounded the string from the end nearest the ring, someone else slid the ring up. They continued unwinding the string until the ring could be easily removed.
