  2. Mathematics of the Incas - Wikipedia

    en.wikipedia.org/wiki/Mathematics_of_the_Incas

    Representation of a quipu, an Inca accounting and mnemonic instrument. The prevailing numeral system was the base-ten. [2] One of the main references confirming this are the chronicles that present a hierarchy of organized authorities, using the decimal numeral system with its arithmometer: Quipu.

  3. Code of the Quipu - Wikipedia

    en.wikipedia.org/wiki/Code_of_the_Quipu

    Code of the Quipu is a book on the Inca system of recording numbers and other information by means of a quipu, a system of knotted strings.It was written by mathematician Marcia Ascher and anthropologist Robert Ascher, and published as Code of the Quipu: A Study in Media, Mathematics, and Culture by the University of Michigan Press in 1981.

  4. Quipu - Wikipedia

    en.wikipedia.org/wiki/Quipu

    The word Quipu is derived from a Quechua word meaning 'knot' or 'to knot'. [16] The terms quipu and khipu are simply spelling variations on the same word.Quipu is the traditional spelling based on the Spanish orthography, while khipu reflects the recent Quechuan and Aymaran spelling shift.

    The primary difference between a computer algebra system and a traditional calculator is the ability to deal with equations symbolically rather than numerically. The precise uses and capabilities of these systems differ greatly from one system to another, yet their purpose remains the same: manipulation of symbolic equations .

    Symbolab is an answer engine [1] that provides step-by-step solutions to mathematical problems in a range of subjects. [2] It was originally developed by Israeli start-up company EqsQuest Ltd., under whom it was released for public use in 2011.

  7. Solver - Wikipedia

    en.wikipedia.org/wiki/Solver

    Linear and non-linear equations. In the case of a single equation, the "solver" is more appropriately called a root-finding algorithm. Systems of linear equations. Nonlinear systems. Systems of polynomial equations, which are a special case of non linear systems, better solved by specific solvers. Linear and non-linear optimisation problems

  8. TK Solver - Wikipedia

    en.wikipedia.org/wiki/TK_Solver

    TK Solver has three ways of solving systems of equations. The "direct solver" solves a system algebraically by the principle of consecutive substitution. When multiple rules contain multiple unknowns, the program can trigger an iterative solver which uses the Newton–Raphson algorithm to successively approximate based on initial guesses for ...

  9. Abacus - Wikipedia

    en.wikipedia.org/wiki/Abacus

    The quipu of the Incas was a system of colored knotted cords used to record numerical data, [45] like advanced tally sticks – but not used to perform calculations. Calculations were carried out using a yupana (Quechua for "counting tool"; see figure) which was still in use after the conquest of Peru. The working principle of a yupana is ...
