  2. Exponentiation - Wikipedia

    en.wikipedia.org/wiki/Exponentiation

    In mathematics, exponentiation, denoted b n, is an operation involving two numbers: the base, b, and the exponent or power, n. [1] When n is a positive integer, exponentiation corresponds to repeated multiplication of the base: that is, b n is the product of multiplying n bases: [1] = ⏟.

    The method is based on the observation that, for any integer >, one has: = {() /, /,. If the exponent n is zero then the answer is 1. If the exponent is negative then we can reuse the previous formula by rewriting the value using a positive exponent.

    Encoding using all Gurmukhi characters plus the Gurmukhi digits. 52: Covers the digits and letters assigned to base 62 apart from the basic vowel letters; [59] similar to base 26 but distinguishing upper- and lower-case letters. 56: A variant of base 58. [clarification needed] [60] 57: Covers base 62 apart from I, O, l, U, and u, [61] or I, 1 ...

  5. Multiplication algorithm - Wikipedia

    en.wikipedia.org/wiki/Multiplication_algorithm

    In arbitrary-precision arithmetic, it is common to use long multiplication with the base set to 2 w, where w is the number of bits in a word, for multiplying relatively small numbers. To multiply two numbers with n digits using this method, one needs about n 2 operations.

  6. Algebraic operation - Wikipedia

    en.wikipedia.org/wiki/Algebraic_operation

    Rather than using the ambiguous division sign (÷), [a] division is usually represented with a vinculum, a horizontal line, as in ⁠ 3 / x + 1 ⁠. In plain text and programming languages, a slash (also called a solidus) is used, e.g. 3 / (x + 1). Exponents are usually formatted using superscripts, as in x 2.

  7. Order of operations - Wikipedia

    en.wikipedia.org/wiki/Order_of_operations

    When exponents were introduced in the 16th and 17th centuries, they were given precedence over both addition and multiplication and placed as a superscript to the right of their base. [2] Thus 3 + 5 2 = 28 and 3 × 5 2 = 75. These conventions exist to avoid notational ambiguity while allowing notation to remain brief. [4]
