  2. Significant figures - Wikipedia

    en.wikipedia.org/wiki/Significant_figures

    Eliminate ambiguous or non-significant zeros by using Scientific Notation: For example, 1300 with three significant figures becomes 1.30 × 10 3. Likewise 0.0123 can be rewritten as 1.23 × 10 −2. The part of the representation that contains the significant figures (1.30 or 1.23) is known as the significand or mantissa.

  3. Normalized number - Wikipedia

    en.wikipedia.org/wiki/Normalized_number

    Simply speaking, a number is normalized when it is written in the form of a × 10 n where 1 ≤ |a| < 10 without leading zeros in a. This is the standard form of scientific notation . An alternative style is to have the first non-zero digit after the decimal point.

  4. Mathematics - Wikipedia

    en.wikipedia.org/wiki/Mathematics

    The apparent plural form in English goes back to the Latin neuter plural mathematica , based on the Greek plural ta mathēmatiká (τὰ μαθηματικά) and means roughly "all things mathematical", although it is plausible that English borrowed only the adjective mathematic(al) and formed the noun mathematics anew, after the pattern of ...

  5. Mathematical software - Wikipedia

    en.wikipedia.org/wiki/Mathematical_software

    A solver is a piece of mathematical software, possibly in the form of a stand-alone computer program or as a software library, that 'solves' a mathematical problem.A solver takes problem descriptions in some sort of generic form and calculates their solution.

  6. Real number - Wikipedia

    en.wikipedia.org/wiki/Real_number

    The notation refers to the set of the n-tuples of elements of (real coordinate space), which can be identified to the Cartesian product of n copies of . It is an n - dimensional vector space over the field of the real numbers, often called the coordinate space of dimension n ; this space may be identified to the n - dimensional Euclidean space ...

  7. Addition - Wikipedia

    en.wikipedia.org/wiki/Addition

    In scientific notation, numbers are written in the form =, where is the significand and is the exponential part. Addition requires two numbers in scientific notation to be represented using the same exponential part, so that the two significands can simply be added.

  8. Mental calculation - Wikipedia

    en.wikipedia.org/wiki/Mental_calculation

    The first step in approximating the common logarithm is to put the number given in scientific notation. For example, the number 45 in scientific notation is 4.5 × 10 1, but one will call it a × 10 b. Next, find the logarithm of a, which is between 1 and 10.
