    en.wikipedia.org/wiki/Scale_factor_(computer...

    For other operations, the scaling is very important. Multiplication, for instance, needs to take into account that both numbers are scaled. As an example, consider two real world values A and B. The real world multiplication of these real world values is: A * B = P

    en.wikipedia.org/wiki/Exercise_(mathematics)

    At the Russian School of Mathematics, students begin multi-step problems as early as the first grade, learning to build on previous results to progress towards the solution. In the 1960s, collections of mathematical exercises were translated from Russian and published by W. H. Freeman and Company : The USSR Olympiad Problem Book (1962), [ 8 ...

    Arithmetic operations are ways of combining, transforming, or manipulating numbers. They are functions that have numbers both as input and output. [37] The most important operations in arithmetic are addition, subtraction, multiplication, and division. [38] Further operations include exponentiation, extraction of roots, and logarithm. [39]

    That is, the 7 is struck through and replaced by a 6. The subtraction then proceeds in the hundreds place, where 6 is not less than 5, so the difference is written down in the result's hundred's place. We are now done, the result is 192. The Austrian method does not reduce the 7 to 6. Rather it increases the subtrahend hundreds digit by one.

  6. Number theory - Wikipedia

    en.wikipedia.org/wiki/Number_theory

    Integers can be considered either in themselves or as solutions to equations (Diophantine geometry). Questions in number theory are often best understood through the study of analytical objects (for example, the Riemann zeta function ) that encode properties of the integers, primes or other number-theoretic objects in some fashion ( analytic ...

    en.wikipedia.org/wiki/Number_sentence

    A valid number sentence that is true: 83 + 19 = 102. A valid number sentence that is false: 1 + 1 = 3. A valid number sentence using a 'less than' symbol: 3 + 6 < 10.
