The Chinese Abacus – Short Essay

The Chinese Abacus The Chinese Abacus is a simple device for performing mathematical calculations. The Chinese Abacus also cognise as a Suanpan in Chinese. The Abacus was offshoot mentivirtuosod by the mathematician Xu Yueh at the end of easterly Han Dynasty (25-220 A. D). The Abacus is a tool for calculating numbers, and was astray officed in ancient clock up to the invention of the modern mechanical and electronic calculators. The Abacus is similar to the modern calculator. It has a rectangular wooden close in with bead in the columns.There is a sucker retinal rod to divide beads into two lift offs, above the rod each bead represents quantities of louvre and as it moves right it goes up exchangeable 50, 500, 5000 and so on, while under the rod each bead represents quantities of one and goes up to 10, 100, 1000, and so on. The basic operations for which the abacus is subservient include arithmetic operations such as addition, subtraction, multiplication, and divis ion. The computational methods using an Abacus atomic number 18 called abacus calculations. This device was created using wood and beads. You solo count the beads that are in the center on the divider.The Abacus is until now in use today by shopkeepers in Asia and Chinatowns in North America. The use of the abacus is still taught in Asian schools, and some few schools in America. Blind children are taught to use the Abacus. One particular use for the Abacus is teaching children simple mathematics and especially multiplication. The Abacus is also an excellent tool for teaching different base numbering systems since it easily adapts itself to some(prenominal) base. I made my Abacus by manifestly getting four wood planks and nailing them unitedly to make a wooden frame.Then I got another wood plank and nailed in the middle to make the go bad rod. I drilled 13 holes on the cross rod, the top, and bottom of the frame. I got a wedge stuck it through the top of the frame, placed two beads in and stuck it through the cross rod, added five more beads thence stuck the stick through the bottom part of the frame thus making the beginning(a) column. I continued this process 12 more times until I accurate all of the 13 columns. After I was done I painted my frame purple and I was finished. A suddenly crafted Chinese Abacus made within one and a half hours. .
