Silent Military Communication

How could a member of the military communicate silently and without light?

By using braille.

Braille was based on a tactile military code called night writing, developed by Charles Barbier in response to Napoleon’s demand for a means for soldiers to communicate silently at night and without light. In Barbier’s system, sets of 12 embossed dots encoded 36 different sounds. It proved to be too difficult for soldiers to recognize by touch and was rejected by the military.

Two Three Ten Sequence

If:
2 3 = 10
7 2 = 63
6 5 = 66
8 4 = 96
9 7 = __

What is the missing number?

f(n, m) = (n + m) × n

e.g. f(2, 3) = (2 + 3) × 2 = 10

Hence, f(9, 7) = (9 + 7) × 9 = 144

As Long As They’re Dead

This is a place. The first letter is after A and before Z but nowhere in between. You can bring as many people as you want, as long as they’re all dead. Where is it?

The cemetery. The letter C is after A and before Z, and it’s not found in the word “between”. The cemetery won’t take live ones. Fortunately I don’t speak from experience on that.

If My Hand Is Forced I Can Sink Ships

I move quickly with hurried steps,
If my hand is forced I can sink ships,
I’ll cause you to shudder when driving your car,
And haul your fuel to where you are,
I’ll watch you bleed from a cut,
Add a rear and I’ll tell you what’s what.

What am I?

Scuttle. To scuttle is to scurry or run hurriedly. Scuttling is the deliberate sinking of your own ship. Scuttle shake is felt in convertibles where the passengers feel a distinct shudder. A coal scuttle is a bucket-like container to haul coal. A shaving scuttle holds hot water when you’re shaving. And adding a “rear” forms scuttlebutt, or rumors and gossip.
