While the definite origin of the abacus is obscure, there is some reason for believing that its earliest form reckoning table covered with sand or fine dust, in which figures were drawn with a stylus, to be erased with the figure when necessary. Though the Abacus is an older tool for calculation it still is used today in Japan taking on a different name called Soroban.\u003c\/p\u003e\n\u003cp style=\"--tw-shadow: 0 0 rgba(0, 0, 0, 0); --tw-ring-inset: var(--tw-empty, ); --tw-ring-offset-width: 0px; --tw-ring-offset-color: #fff; --tw-ring-color: rgba(59, 130, 246, 0.5); --tw-ring-offset-shadow: 0 0 rgba(0, 0, 0, 0); --tw-ring-shadow: 0 0 rgba(0, 0, 0, 0); margin: 0px 0px 13px; padding: 0px; line-height: 17px; color: rgb(83, 86, 90); font-family: Arial, Verdana; font-size: 14px; background-color: rgb(255, 255, 255);\"\u003eThough the Japanese Abacus or Soroban may appear mysterious or even primitive to those raised in the age of pocket calculators and desktop computers, this intriguing tool is capable of amazing speed and accuracy.
