Three Five Six To One Hundred

Without changing the order of these numbers, how can they equal 100?

3 5 6 2 54 5

= 3 * (5 – 6) + 2 * 54 – 5
= -3 + 108 – 5
= 105 – 5
= 100

A Medication of Three Parts

I’m a medication with three parts. The first part is the surname of someone who has been a Mary and a Maria. The second part is a vital organ and the last is plentiful in the ocean.

What am I?

Andrews Liver Salts, an antacid. Julie Andrews played the role of Mary Poppins in the movie of the same name, and Maria in the Sound of Music. It’s tough to live without a liver and a taste of the ocean always includes a touch of salt.

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.

Six Nine Twenty-Seven

What is N?

6, 9, 27, 54, N, 2241

675.

The next number in the sequence is n squared minus m or f(n,m) = n2 – m
f(6,9) = 62 – 9 = 27
f(9,27) = 92 – 27 = 54
f(27,54) = 272 – 54 = 675
f(54,675) = 542 – 675 = 2241

Others from Thor and his hammer are hewn,

By Odin’s beard, and Frigg and Tiw,
The last is Saturn, from which we grew.

Rooms One Score and Six

This house holds rooms, one score and six,
That shelter a vast mob.
It lets lions lie down with the lambs,
Yet makes both shun the slob.

None now will nestle with nicks and nates,
While reams room near the rear.
Though you and I have separate rooms
Both our bottles brim with beer.

The king and queen can never mate
(Though hands and hearts hobnob)
Because their rooms are separate
If this jail does its job.

What house is this that rules thus
Forcing faith to fend with fear?
The answer to this riddle lies
With dead and dying here.

A dictionary.
