Messy Math

What is the answer to this problem?

48 / 2(9 + 3) = ?

It depends. Usually, math has one right answer, but in this case, the order of operations can get a little quirky.

There are two ways to solve this. First, like so:
48 / 2 × (9 + 3) = ?
48 / 2 × (12) = ?
24 × 12 = 288

But another, arguably valid way is:
48 / 2 × (9 + 3) = ?
48 / 2 × (12) = ?
48 / 24 = 2

Thanks to KnowYourMeme for providing a great overview on this one. Math StackExchange has more discussion.

Sever Bones and Marrow

My first is in wield, sever bones and marrow.
My second is in blade, forged in cold steel.
My third is in arbalest, and also in arrows.
My fourth is in power, plunged through a shield.
My fifth is in honor, and also in vows
My last will put an end to it all.

What am I?

Three Brothers Share A Family Sport

Three brothers share a family sport:
A non-stop marathon
The oldest one is fat and short
And trudges slowly on
The middle brother’s tall and slim
And keeps a steady pace
The youngest runs just like the wind,
A-speeding through the race
“He’s young in years, we let him run,”
The other brothers say
“‘Cause though he’s surely number one,
He’s second, in a way.”

The hands on a clock (hour, minute, second).

Famous for the Friendly Folk

I have palms but not on hands,
I offer foods from distant lands,
When at my peak you’ll see me smoke,
I’m famous for my friendly folk,
My flowers grow and yet they lay,
There’s fire where a man will play,
I’m sure you know we’re family,
You’re welcome to come stay with me.

What am I?

Hawaii.

Shared Birthdays

In 2012 a class was divided into 2 groups. Their assignment was to find the names of at least 3 children who were born on the same day from 5 different months of 2011. These were the results:

Group 1
August 20: Oliver, William, and Adam.
January 3: John, Alice, and Ken.
September 7: Bruce, Shane, and Peter.
June 11: April, Patrick, and Bobby.
July 19: Trent, Julie, and Charles.

Group 2
March 1: Karl, Willie, and Patty.
February 29: Blake, Kobe, and Wayne.
December 24: Kyle, Chad, and Zoe.
May 12: Matthew, Manny, and Adrian.
November 20: Greg, Fiona, and Elizabeth.

The members of group 2 got an F on the assignment. Why?

Group 2 failed because 2011 wasn’t a leap year, meaning there was no February 29th.

The Sun Bakes Them

The sun bakes them,
The hand breaks them,
The foot treads them,
The mouth tastes them.

Grapes. Grapes are grown in the sun, can be hand picked and crushed by feet (which is sort of gross) to make wine, which is tasted by your mouth when you drink it.

Hold In Your Left Hand

What can you hold in your left hand and not in your right?

Your right elbow. You can try it yourself if you’re not convinced, but unless you have a broken arm or an incredibly flexible ulna, you won’t reach it.

Walks on Graves at Night

This walks on graves at night yet in homes during the day,
Men are scared of it, women like it, children play with it,
It lives on dates and salt,
It is covered in hair,
Its name starts with ‘M’ and it is mentioned in the Quran.

What is it?

Moths.
Most species of moths are nocturnal, yet they are attracted to light and can be found in homes. Men, in the most generic sense, can be scared of moths (see Mottephobia) as well as the damage they can cause as pests to bee hives, grain, flour, trees and agriculture. Women like moths because of the silk they produce. Children frequently chase and play with moths. Moths are attracted to salt and love to eat rotting fruit (such as dates). Some species of moths are densely covered with tiny hairs and of course it starts with the letter ‘m’. Lastly, moths are mentioned in the Quran (101:4 (Asad) [It will occur] on the Day when men will be like moths swarming in confusion)
