Progressive Countdown

If you’re given a number, subtract 1, then 2 from the result, then 3 from that result and so on until you reach 0 or a negative number.

For example, if you’re given 15:

15 – 1 = 14
14 – 2 = 12
12 – 3 = 9
9 – 4 = 5
5 – 5 = 0

Which of these numbers will finish exactly at zero?

102 103 104 105 106

105

105 – 1 = 104
104 – 2 = 102
102 – 3 = 99
99 – 4 = 95
95 – 5 = 90
90 – 6 = 84
84 – 7 = 77
77 – 8 = 69
69 – 9 = 60
60 – 10 = 50
50 – 11 = 39
39 – 12 = 27
27 – 13 = 14
14 – 14 = 0

I’m Usually Quite Pleasant

I’m usually quite pleasant
As you roam and play,
But if you look into my eyes,
I’ll not look away.

Once you turn away from me,
I’ll attack if I stay dry,
Better grab a pail of water,
I’ll not stop until I die.

What am I?

An Enderman, from Minecraft.

Enderman are normally passive, but they become hostile if a player looks directly at them. The Enderman will stare back until the player looks away, and then attack the player. A bucket of water is the best way to defeat an Enderman.

Seemingly Simple Math

What is the answer to this math problem:

8 ÷ 2 (2 + 2)

16 or 1, depending.

According to PEMDAS, parentheses come first: 8 ÷ 2 (4)

Then, even though multiplication is first in PEMDAS, you go left to right: 4 (4) = 16

If you got 1, you’re in good company. That’s what I got at first too but most calculators I’ve tried get 16.

I found this at Popular Mechanics and the debate continues online.

I Make You See the Beauty of Nature

I make you see the beauty of nature through colors,
My name makes things weigh less
And I have no weight at all.

What am I?

Light. Without light you wouldn’t be able to see anything. And light is made up of all the colors of the rainbow. Adding light to a word can mean it weighs less and light has no mass.

Moved Like the Tide

Dear Brother,
In the past, men believed
that it moved like the tide.
Till its movement desists,
we will always be this.

Blood.

Five Hundred Begins It

Five hundred begins it, five hundred ends it,
Five in the middle is seen;
First of all figures, the first of all letters,
Take up their stations between.
Join all together, and then you will bring
Before you the name of an eminent king.

DAVID (Roman numerals).
