  2. List of logarithmic identities - Wikipedia

    en.wikipedia.org/wiki/List_of_logarithmic_identities

    These are the three main logarithm laws/rules/principles, [3] from which the other properties listed above can be proven. Each of these logarithm properties correspond to their respective exponent law, and their derivations/proofs will hinge on those facts. There are multiple ways to derive/prove each logarithm law – this is just one possible ...

  3. Mirifici Logarithmorum Canonis Descriptio - Wikipedia

    en.wikipedia.org/wiki/Mirifici_Logarithmorum...

    This arrangement is such that for each line on a page, the full angle represented by column 7 is the co-angle of column 1 (90° – column_1). Moving inward, adjacent to each angle column is the sine of that angle, followed by the absolute value of Napierian log of that sine.

  4. Arithmetic - Wikipedia

    en.wikipedia.org/wiki/Arithmetic

    The main arithmetic operations are addition, subtraction, multiplication, and division. Arithmetic is an elementary branch of mathematics that studies numerical operations like addition, subtraction, multiplication, and division. In a wider sense, it also includes exponentiation, extraction of roots, and taking logarithms.

  5. Order of operations - Wikipedia

    en.wikipedia.org/wiki/Order_of_operations

    Sometimes multiplication and division are given equal precedence, or sometimes multiplication is given higher precedence than division; see § Mixed division and multiplication below. If each subtraction is replaced with addition of the opposite (additive inverse), then the associative and commutative laws of addition allow terms to be added in ...

  6. Principles of Hindu Reckoning - Wikipedia

    en.wikipedia.org/wiki/Principles_of_Hindu_Reckoning

    Unlike Abu'l-Hasan al-Uqlidisi's Kitab al-Fusul fi al-Hisab al-Hindi (The Arithmetics of Al-Uqlidisi) where the basic mathematical operation of addition, subtraction, multiplication and division were described in words, ibn Labban's book provided actual calculation procedures expressed in Hindu-Arabic numerals.

  7. History of logarithms - Wikipedia

    en.wikipedia.org/wiki/History_of_logarithms

    The history of logarithms is the story of a correspondence (in modern terms, a group isomorphism) between multiplication on the positive real numbers and addition on the real number line that was formalized in seventeenth century Europe and was widely used to simplify calculation until the advent of the digital computer.

  8. Distributive property - Wikipedia

    en.wikipedia.org/wiki/Distributive_property

    In approximate arithmetic, such as floating-point arithmetic, the distributive property of multiplication (and division) over addition may fail because of the limitations of arithmetic precision. For example, the identity 1 / 3 + 1 / 3 + 1 / 3 = ( 1 + 1 + 1 ) / 3 {\displaystyle 1/3+1/3+1/3=(1+1+1)/3} fails in decimal arithmetic , regardless of ...

  9. Division (mathematics) - Wikipedia

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

    In abstract algebra, given a magma with binary operation ∗ (which could nominally be termed multiplication), left division of b by a (written a \ b) is typically defined as the solution x to the equation a ∗ x = b, if this exists and is unique. Similarly, right division of b by a (written b / a) is the solution y to the equation y ∗ a = b ...
