A Chinese abacus is called a Suan Pan. It works because it is based upon the decimal system, so the beads are used to count groups of ten.

The number works out as 9

The number works out as 14

Police 112 or 113 works on mobiles and landlines Fire 115 works on mobiles and landlines Ambulance 118 works on mobiles and landlines

Not too sure about your question but let the number be x:- If: 7x+8 = 50 then x works out as 6 But if: 7x = 42+8 then x works out as 7 and 1/7

Chinese AbacusAbacus was invented by Chinese. But vedic mathematics is known to deal with equipment similar to abacus. Not withstanding anything Chinese abacus just an amazing piece of calculator that needs no power except mind power. The Chinese abacus actually sharpens your mind power and calculations can be done faster than a home computer of P 4 standard because it takes time to punch in the numbers manually into the computer. But abacus is just moving beads.Here is a nice free Chinese abacus that actually works on clicking on it. If you want to know how it works Just cut and paste this link in the address bar of browser. It is free and works. This is one working Chinese abacus ideally suited for school children and adults alike.http://100softwares.googlepages.com/free_chinese_abacus.htmJust try clicking on any bead and you will find the answer right under it in the box. I think it runs on java so download java to run the free Chinese abacus on your PC.

"Scientific Calculator the evolution of Abacus "

It works in powers of 10, so figures such as 100 and 1000 are especially important. There are 100 centimetres in a metre and 1000 metres in a kilometre for example.AnswerThe SI system is based on ten, raised to the power of multiples of three. In other words, micro-. milli-, kilo-, mega-, etc. Centi-. etc., are NOT used in the SI system.

A device that works on the idea that something is on or off. In computers 0=off 1=on. The abacus was considered digital because the beads were either on of off.

The advent of computers caused a return to binary from decimal. The abacus, the first digital calculator, was in use in Ancient China and is based on The Tao, the basis of the Chinese religion that one requires a place to put something before you can have something. Tao Te Ching: In the beginning was the Ought: chi(the one) entered the Ought, and the one became yin(the two), the two became yang (the three), and the three became the ten-thousand things (everything of one kind) in The Cosmic Image. It basically has similar reasoning to science's Big Bang Theory! The Chinese abacus and the Roman abacus look totally different, but they both seem to be based on two hands with five fingers on each; Roman numerals follow the same pattern. Could you explain in detail how the Chinese abacus also works on a one-two-three principle ?

There is an ancient learning tool, first used in the year 2,700 BC, that transforms the way that young children understand numeracy. "The world's oldest calculator" can help children develop number sense, build estimation skills, and even strengthen the physical synapses in the brain! When used correctly, this powerful device can form the foundation of a child's mathematical success for life. It isn't a computer or a workbook, and there is no magic involved. The tool is the humble abacus, which has been making mathematics visible for millennia! The most famous abacus might be the Chinese abacus, but there is evidence of its use in Ancient Rome, Russia, and Japan. There are even high-tech computer systems that rely on binary abacus technology to this day! You can be the next one to harness the abacus's power when you bring one home for your child! If you don't know how to use one, it's not too late to learn! Keep reading to discover the ins and outs of the abacus, and how you can incorporate it into your child's early math education! What Is an Abacus? In essence, an abacus is a very primitive calculator or computer. Mathematicians sometimes call abacuses "counting frames." A basic abacus consists of a frame with various vertical rods that are strung with beads that can move up and down. It is a tactile tool that makes quantities visible to the sighted. Today, the abacus has many applications for the blind. It's also a wonderful learning tool for young children exploring quantity for the first time. Historians are unsure who is responsible for inventing the abacus, or exactly when it was first invented. It probably originated in Ancient China or Babylon. The abacus may have had many inventors across many cultures, as you can find a version of the tool in nearly every country on earth. The word "abacus" probably comes from the Ancient Greek word "abax," which means "flat surface." The Ancient Romans translated this word into the Latin abacus. It is still called an abacus today. How an Abacus Works The frame of the abacus contains several rods strung with beads, which move up and down independently. Each rod is representative of a place value, which decreases from left to right. A single abacus can represent values into the millions, down to the decimal place! Some abacuses separate the beads into two rows of five. Moving a bead from the top row to the center counts as a quantity of five. Moving a bead from the bottom row to the top allows an individual to count up to ten. Using this system as a basis, it's possible to perform all of the basic mathematical operations on an abacus. Its strength is that it makes these calculations tactile, tangible, and visible. An ancient merchant might have used an abacus so that a customer couldn't contest a charge at the marketplace. The first computer programming languages are also based on the abacus. Computers were originally programmed using a binary system, described as a series of zeros and ones. These roughly equate to the low and high rows of the abacus, another binary system! The Abacus in Early Childhood Nobody expects a preschooler to use an abacus to count to one million or work with decimals. For young children, this tactile tool has another important developmental function. It can help them form flexible models of quantities that make complex mental math possible as they age. According to developmental theorist Jean Piaget, children experience four basic stages of cognitive development. Preschool and early elementary-aged children fall into the preoperational stage. At this stage, children gain the ability to engage in symbolic thought but need concrete visuals to make concepts tangible. An abacus can be that concrete visual. As long as children can see and manipulate quantities, they are capable of understanding them. When kids engage meaningfully with numeracy during sensitive periods of development, they retain these mental models for life. The best abacus for kids under seven is a horizontal wooden abacus. Here are a few meaningful ways to use an abacus with a young child. Teach Patterning With an Abacus One of the most fundamental skills in both math and reading is patterning. Children who can identify, name, and complete patterns are more prepared for complex learning than their peers. You can use a colorful abacus to encourage these early patterning skills. You may want to create and photograph a series of simple patterns for your child to copy. This encourages an early counting principle called one-to-one correspondence. It forms the basis for all numeric understanding moving forward. Understanding Tens Using an Abacus The mathematics used today is base ten mathematics. Understanding how to decompose a quantity of ten is a skill that will come in handy as a child begins formal mathematical education. You can introduce the concept using a guessing game.
