THREE CATS SET THE ART OF POETRY TO NUMBER EQUATIONS

The art of raising equations.

The language of algebra is the equation. "To solve a problem concerning numbers or abstract relationships of quantities, the problem simply translate from English or another language to algebraic language," wrote the great Newton in his manual titled Arithmetic Universal algebra. Isaac Newton showed by example how the translation was made. Here's one:

In the vernacular In the language of algebra

A trader had a certain amount of money

X

The first year was spent 100 pounds X - 100

increased the rest with a third of it (X - 100) +1 / 3 (X-100) = 1 / 3 (4x-400)

The following year he returned to spend 100 pounds 1 / 3 (4x-400) -100 = 1 / 3 (4x-700)

and increased the amount remaining in a third of it 1 / 3 (4x - 700) +1 / 9 (4X-700) = 1 / 9 (16X-2800)

The third year it spent 100 pounds again 1 / 9 (16X-2800) -100 = 1 / 9 (16X-3700)

After he had added his third 1 / 9 (16X-3700) +1 / 27 (16X-3700) = 1 / 27 (64X-14800)

part

the capital was twice the initial 1 / 27 (64X-14800) = 2X

Solution

To determine the initial capital of the trader is not only solve the latter equation.

The solution of an equation is often easy task, however, raise the equation based on data from a problem is often more difficult. We have seen that raising the art of equations is indeed translating "the vernacular language of algebra." But the language of algebra is laconic in the extreme, so not all the turns of language are easily translated. The translations can be very different by the level of difficulty, as can convince the reader to view examples of first-degree equation set.

Removing Smells From Ski Gloves

PI

The Number Pi

(Poem by Wislawa Szymborska )

The number Pi is impressive
three point one four one
all following figures are also starting
five nine two it never ends.

can not cover his eyes six five three five
with estimates
with eight nine seven nine
imagination joke or three two three, that is, by comparison four six
anything else
two six four three in the world.

The longest snake after several meters

also interrupted, but a little later,
make fabulous snakes.

The procession of figures that make up the number Pi
does not stop at the margin of a page,
is able to continue for the table, through the air,
through the wall, a sheet, the nest of a bird
the clouds, straight to heaven
through the total swelling and vastness of the sky.

Oh how short is the comet's tail, like a mouse! How fragile

star Ray
that bends in any space!

But here two three fifteen three hundred and ninety
my phone number your shirt size
years 1973
sixth floor number of inhabitants sixty-five tenths
the hip measurement two fingers the charade and
code where my
nightingale flies and sings and calls for calm behavior
also pass the earth and sky
but not the number Pi, it does not,
he is still a good five
not any
eight or the last seven
getting haste oh, getting quickly to the sluggish eternity
for permanence. _________
