  2. Cross-multiplication - Wikipedia

    en.wikipedia.org/wiki/Cross-multiplication

    In mathematics, specifically in elementary arithmetic and elementary algebra, given an equation between two fractions or rational expressions, one can cross-multiply to simplify the equation or determine the value of a variable. The method is also occasionally known as the "cross your heart" method because lines resembling a heart outline can ...

    Starlark: Starlark is a dialect of Python created by Google for Bazel. Model checkers like FizzBee uses Starlark/Python as the modeling language. TLA+: General-purpose specification language based on the Temporal Logic of Actions, originally used for distributed and concurrent systems. The language for the specifications and their properties is ...

    Rosetta Code is a wiki-based programming chrestomathy website with implementations of common algorithms and solutions to various programming problems in many different programming languages. [ 2 ] [ 3 ] It is named for the Rosetta Stone , which has the same text inscribed on it in three languages, and thus allowed Egyptian hieroglyphs to be ...

  5. Criss-cross algorithm - Wikipedia

    en.wikipedia.org/wiki/Criss-cross_algorithm

    The criss-cross algorithm visits all 8 corners of the Klee–Minty cube in the worst case. It visits 3 additional corners on average. The Klee–Minty cube is a perturbation of the cube shown here. In mathematical optimization, the criss-cross algorithm is any of a family of algorithms for linear programming.

  6. Computational complexity of mathematical operations - Wikipedia

    en.wikipedia.org/wiki/Computational_complexity...

    The complexity of an elementary function is equivalent to that of its inverse, since all elementary functions are analytic and hence invertible by means of Newton's method. In particular, if either exp {\displaystyle \exp } or log {\displaystyle \log } in the complex domain can be computed with some complexity, then that complexity is ...

    House Energy and Commerce Committee ranking member Frank Pallone Jr., D-N.J., also urged the FDA to ban Red No. 3, which is made from petroleum and gives food and drinks a bright cherry color.

  8. Multiplication algorithm - Wikipedia

    en.wikipedia.org/wiki/Multiplication_algorithm

    Another method of multiplication is called Toom–Cook or Toom-3. The Toom–Cook method splits each number to be multiplied into multiple parts. The Toom–Cook method is one of the generalizations of the Karatsuba method. A three-way Toom–Cook can do a size-3N multiplication for the cost of five size-N multiplications. This accelerates the ...
