    Subtract the remaining digits from 9. Add half of the neighbor, plus 5 if the digit is odd. For the leading 0, subtract 1 from half of the neighbor. Example: 346 × 4 = 1384 Working from right to left: (10 − 6) + Half of 0 (0) = 4. Write 4. (9 − 4) + Half of 6 (3) = 8. Write 8. (93) + Half of 4 (2) + 5 (since 3 is odd) = 13. Write 3 ...

    This work was subsequently published in 2019, including systems for Chomsky type-2 and type-3 languages. [13] In 2020, University of Glasgow researchers created a chemical computer using 3D-printed parts and magnetic stirrers in order to control the oscillations of BZ medium. In doing so, they were able to compute binary logic gates, and ...

    The Chisanbop system. When a finger is touching the table, it contributes its corresponding number to a total. Chisanbop or chisenbop (from Korean chi (ji) finger + sanpŏp (sanbeop) calculation [1] 지산법/指算法), sometimes called Fingermath, [2] is a finger counting method used to perform basic mathematical operations.

    en.wikipedia.org/wiki/Equation_of_State...

    Monte Carlo methods are a class of computational algorithms that rely on repeated random sampling to compute their results. In statistical mechanics applications prior to the introduction of the Metropolis algorithm, the method consisted of generating a large number of random configurations of the system, computing the properties of interest (such as energy or density) for each configuration ...
