What is interest?

disclaimer-Simple- interest could the amount of money the loan sharks earn per month...
Interest could be what you own me...

But simple interest is easy... But compound interest???
Compound interest is the concept of adding accumulated interest back to the principal, so that interest is earned on interest from that moment on. The act of declaring interest to be principal is called compounding (i.e., interest is compounded). A loan, for example, may have its interest compounded every month: in this case, a loan with $100 principal and 1% interest per month would have a balance of $101 at the end of the first month.

The link is a website to calculate compound interest, please check this out!
http://www.moneychimp.com/calculator/compound_interest_calculator.htm

An example of interest rate is here:

Current Bank Rate:
0.5%

Next due: 9 Apr '09

Current Inflation (CPI):
3.2%
Next due: 21 Apr '09

Inflation Target: 2.0%

Please enjoy!

Definition of speed in case some of you are pure 'SOTONGS' or "retards" T_T

Speed is the rate of motion, or equivalently the rate of change of distance.

Speed is a scalar quantity with dimensions length/time; the equivalent vector quantity to speed is velocity. Speed is measured in the same physical units of measurement as velocity, but does not contain the element of direction that velocity has. Speed is thus the magnitude component of velocity.

In mathematical notation, if an object traveling at constant speed moves a distance x in time t, its speed, denoted by v, is simply given by

v = \frac {x}{t}.

In many situations, objects do not move at a constant speed. For example, if a car goes 120 miles in 4 hours, its average speed during that time is 30 miles per hour, but its instantaneous speed may have varied. For an object which is accelerating or decelerating, the instantaneous speed is given by

v = \left\frac {dx}{dt}\right,

where dx is the distance it travels in a very short period of time dt. If the object travels a total distance x in time t, its average speed over that time is given by

\bar{v} = \left\frac {x}{t}\right.

Now a quiz.

5/5 Print it out? Calculator are provided....

Prizes Will be given......While stocks Last! MUAHAHAHAHHAHAHAHAHHA

1) What is the value of (1x2x3x4x5...............x10x11..............x100000x1000001x999999)/(2x4x6.....................x 99 *u)
When u is a prime.

2) What is the value is (1!*2!*3!*4!*5!*..................................................................100!)??????

3) What is km10 =_____ Mm?

4) A rocket leaves the space station at the 4pm and a space shuttle leaves the space station at 5pm . How long does it take for the space shuttle to catch up with the rocket..If a space shuttle travels at (147!)km and a rocket travels at (146!)km?

5) What is 987*79/41*78/76*67*68/7686*768786/687868*66768667/6786345*345345?

Give us some questions... The best question that is given will receive a prize.

Anyone who gets 10 points for this blog will get to borrow the book for a day!!!

The Trachtenberg System is a system of rapid mental calculation, somewhat similar to Vedic mathematics. It was developed by the Ukrainian engineer Jakow Trachtenberg in order to keep his mind occupied while being held in a Nazi concentration camp.

The system consists of a number of readily memorized patterns that allow one to perform arithmetic computations very quickly.

The rest of this article presents some of the methods devised by Trachtenberg. These are for illustration only. To actually learn the method requires practice and a more complete treatment.

The most important algorithms are the ones for general multiplication, division and addition. In addition, the method includes some specialized methods for multiplying small numbers between 5 and 13.

1.   Every month, a girl gets allowance. Assume last year she had no money, and kept it up to now. Then she spends 1/2 of her money on clothes, then 1/3 of the remaining money on games, and then 1/4 of the remaining money on toys. After she bought all of that, she had $7777 left. Assuming she only gets money by allowance, how much money does she earn every month?

Here is a question that you might want to consider... This is not a quiz.

What is Maths?
That is what we learn everyday in school.
No matter if its whole numbers, algebra or whatsoever.
Here I am gonna show you the definations of maths.
(From
http://en.wikipedia.org/wiki/Mathematics)

Mathematics is the study of
quantity, structure, space, change, and related topics of pattern and form. Mathematicians seek out patterns whether found in numbers, space, natural science, computers, imaginary abstractions, or elsewhere. Mathematicians formulate new conjectures and establish their truth by rigorous deduction from appropriately chosen axioms and definitions. The mathematician Benjamin Peirce called mathematics "the science that draws necessary conclusions". However, Albert Einstein stated that "as far as the laws of mathematics refer to reality, they are not certain; and as far as they are certain, they do not refer to reality."
Through the use of
abstraction and logical reasoning, mathematics evolved from counting, calculation, measurement, and the systematic study of the shapes and motions of physical objects. Knowledge and use of basic mathematics have always been an inherent and integral part of individual and group life. Refinements of the basic ideas are visible in mathematical texts originating in the ancient Egyptian, Mesopotamian, Indian, Chinese, Greek and Islamic worlds. Rigorous arguments first appeared in Greek mathematics, most notably in Euclid's Elements. The development continued in fitful bursts until the Renaissance period of the 16th century, when mathematical innovations interacted with new scientific discoveries, leading to an acceleration in research that continues to the present day.
Today, mathematics is used throughout the world as an essential tool in many fields, including natural science, engineering, medicine, and the social sciences such as economics and psychology. Applied mathematics, the branch of mathematics concerned with application of mathematical knowledge to other fields, inspires and makes use of new mathematical discoveries and sometimes leads to the development of entirely new disciplines. Mathematicians also engage in pure mathematics, or mathematics for its own sake, without having any application in mind, although practical applications for what began as pure mathematics are often discovered later.
