Odd Start, Even Finish

What three letter English word has an odd start, an even finish and an infinitely long middle?

The word vex. “v” is Roman numeral 5, which is odd. “x” is Roman numeral 10, which is even. “e” is the base of the natural logarithm and is irrational (e = 2.718281828…). Its mantissa (the part to the right of the decimal point) is infinitely long.

Fly In The Ear

One evening a man is walking home from work and an insect flies into his ear. He tries to pry it out but it doesn’t work. Shaking his head isn’t successful either. Finally he managed to get it out. How did he do it?

As soon as he got home, he shined a flashlight close to his ear and the insect, attracted by the light, flew toward it.

An Extraordinary Event

On the sixth of May in the year 1978 at exactly thirty-four minutes past noon, a most extraordinary event occurred. This singular occasion will probably never be witnessed by anyone who was alive at that time. What happened?

The time and date was 12:34 5/6/78, counting from one to eight. The next time this event will occur is 12:34 6 May 2078. Unless someone alive in 1978 lives to be over a hundred, they won’t be alive when it happens again.

I Always Tell the Truth

You see me quite often,
But don’t really care.
If you pass by me,
You’ll often stop and stare.

I can’t speak or see,
But don’t think me uncouth,
Because no matter what,
I always tell the truth.

What am I?

A mirror.

Humans and Animals

I am important to both human beings and animals. Both search for me but it is hard to find me. I travel to benefit them. What am I?

A scent or smell. A scent is important to both humans and animals and both search for scents (for different reasons). A scent travels through the air to benefit humans and animals, again, for different reasons.

Special thanks to Vavessa for the answer to this one.

Ten Times Two is 0218

10 × 2 = 0218
20 × 2 = 1421
30 × 2 = 1632
40 × 2 = ?

2840.

This makes the first column the start of the Fibonacci series: 0, 1, 1, 2.
The second column is the even numbers: 2, 4, 6, 8
The third column is counting up by ones: 1, 2, 3, 4
And the last column is the answer in the first row in reverse: 8, 1, 2, 0.

Don’t ask what 50 × 2 equals. I have no idea. :)

Thanks to Jim for helping with the solution.

Say my name and I disappear. What am I?

Silence.

An alternate version is, “What is so fragile it breaks when you say its name?”

Alter By a Single Stroke

How can you alter the following equation by a single stroke to make it correct?

5 + 5 + 5 = 550

5 4 5 + 5 = 550

Add a diagonal line on the top left of the first plus sign to convert + into a 4. You could also put a slash through the equal sign to make ≠ (not equal) but that’s not as cool.
