Challenge #20: PEON to LORD to KING

Are those dates BC, Bobby? If AD, then that person whose apparition I saw at St. Louis died from vampirism before he was bitten by the Countess after their tragic love affair.

EDIT: Hey! You changed your post from him dying in 1661 to 1683! Or was that date I thought I saw only an aberration?

2054...the product of the outer two digits plus the sum of the inner two = 13.

1989 (my Y.O.B.)

ie, 21 years ago.

And the sum of the digits of the 180 degree sideways rotation of that number is also 21 (ie, 6+8+6+1 = 21).

1911

1911-(the reverse of 1911)-(the 180 degree sideways rotation of 1911)+(the reverse of the 180 degree sideways rotation of 1911) = (the reverse of the 180 degree sideways rotation of (the sum of the digits of the 4 resolved elements of the left-hand side of the equation plus the sum of the digits of the degrees on the left-hand side of the equation)) × 13.

Why good for you, Bobby? Was that the celebration of 100 years before you were born? Did someone know something?

It was doubly good for me because I wasn't in England then and missed the cholera outbreak there, and also because I wasn't born yet and that made sure I missed it.

1859

I would never have gone on a Ferris wheel ride if it wasn't for George Washington Gale Ferris, Jr., the inventor of the Ferris wheel, who was born that year.

Hi theoldbrewer,

Type this example, but leave out the space after the first bracket (I had to include the space so that my example wouldn't be hidden):

[ hide]Unique New York[/hide]

Here's what your attempt should look like after you remove the blank space after the first bracket:

If you want to give the hide tab a title, you can do it like this:

[ hide=Tongue twister]Unique New York[/hide]

This is what it should look like:

Hi Bobby,

Re the i.o.u. reference?

Candy spent $35 plus 1/3 of a dollar at store #2 and $17 plus 2/3 of a dollar at store #3.

AFAIK, thirds of a dollar can't be made up from actual cold, hard, cash and so I guessed that there must have been some other means of payment. eg, an i.o.u.

Hi Bobby,

Hi Bobby,

I think that A is

I used BCalc, a freeware scientific calculator.

I also checked my answer with WolframAlpha...which automatically changed my 'int' function to the 'floor' function.

Hi Bobby,

I did

I had a look at your answers but was in too much of a hurry and didn't understand them. I'll have a better look at them later...

A bit cryptic, that, but here's my take on it:

Bobby's talking - in code - about....tulips!

1560 AD: The first tulip bulb is brought from Turkey to the Netherlands (Wikipedia).
A great number: Scads of them at springtime in Holland, in fact.
sublime: Add lime to overly-acidic soil, just below the surface.
extraordinary: Buy 12 ordinary tulips and get one free.
subtle: Tulips generally have only the hint of an odour (Alexander Dumas: "I shall make experiments. With them I shall succeed in imparting scent to the tulip.")
magnificent: Right on! (see piccy)

That's the one I wanted. So you're a tulip-lover, Bobby!

I now nearly feel encouraged enough to try and crack bob farey's 'uncrackable' substitution cypher code!

New number: 1573

1573 AD is a well-renowned time in history, marking the 13th year since the first tulip bulb was brought from Turkey to the Netherlands.
Also (according to the Amsterdam Tulip Museum), during that year Pope Maximillian II sent Clusius to Vienna to direct hortus, but eventually his tulip bulbs were stolen.
