  2. Scientific notation - Wikipedia

    en.wikipedia.org/wiki/Scientific_notation

    The letters "E" or "D" were used as a scientific-notation separator by Sharp pocket computers released between 1987 and 1995, "E" used for 10-digit numbers and "D" used for 20-digit double-precision numbers. [16] The Texas Instruments TI-83 and TI-84 series of calculators (1996–present) use a small capital E for the separator. [17]

  3. List of representations of e - Wikipedia

    en.wikipedia.org/wiki/List_of_representations_of_e

    A unique representation of e can be found within the structure of Pascal's Triangle, as discovered by Harlan Brothers. Pascal's Triangle is composed of binomial coefficients, which are traditionally summed to derive polynomial expansions. However, Brothers identified a product-based relationship between these coefficients that links to e.

  4. Greek letters used in mathematics, science, and engineering

    en.wikipedia.org/wiki/Greek_letters_used_in...

    Greek letters are used in mathematics, science, engineering, and other areas where mathematical notation is used as symbols for constants, special functions, and also conventionally for variables representing certain quantities. In these contexts, the capital letters and the small letters represent distinct and unrelated entities.

    Latin and Greek letters are used in mathematics, science, engineering, and other areas where mathematical notation is used as symbols for constants, special functions, and also conventionally for variables representing certain quantities.

    1. Internal direct sum: if E and F are abelian subgroups of an abelian group V, notation = means that V is the direct sum of E and F; that is, every element of V can be written in a unique way as the sum of an element of E and an element of F.

  7. E - Wikipedia

    en.wikipedia.org/wiki/E

    A scientific calculator display showing the Avogadro constant (6.022 140 76 × 10 23 reciprocal moles) in E notation. In the hexadecimal (base 16) numbering system, "E" corresponds to the number 14 in decimal (base 10) counting. "e" is also commonly used to denote Euler's number.

  8. Engineering notation - Wikipedia

    en.wikipedia.org/wiki/Engineering_notation

    Engineering notation or engineering form (also technical notation) is a version of scientific notation in which the exponent of ten is always selected to be divisible by three to match the common metric prefixes, i.e. scientific notation that aligns with powers of a thousand, for example, 531×10 3 instead of 5.31×10 5 (but on calculator displays written without the ×10 to save space).

  9. Long and short scales - Wikipedia

    en.wikipedia.org/wiki/Long_and_short_scales

    Scientific notation (also known as standard form or exponential notation, for example 1 × 10 9, 1 × 10 10, 1 × 10 11, 1 × 10 12, etc.), or its engineering notation variant (for example 1 × 10 9, 10 × 10 9, 100 × 10 9, 1 × 10 12, etc.), or the computing variant E notation (for example 1e9, 1e10, 1e11, 1e12, etc.). This is the most common ...
