  3. Positional notation - Wikipedia

    en.wikipedia.org/wiki/Positional_notation

    (465 7 = 243 10) 10 b = b for any base b, since 10 b = 1×b 1 + 0×b 0. For example, 10 2 = 2; 10 3 = 3; 10 16 = 16 10. Note that the last "16" is indicated to be in base 10. The base makes no difference for one-digit numerals. This concept can be demonstrated using a diagram. One object represents one unit.

    en.wikipedia.org/wiki/Scientific_notation

    While base ten is normally used for scientific notation, powers of other bases can be used too, [25] base 2 being the next most commonly used one. For example, in base-2 scientific notation, the number 1001 b in binary (=9 d) is written as 1.001 b × 2 d 11 b or 1.001 b × 10 b 11 b using binary numbers (or shorter 1.001 × 10 11 if binary ...

  5. Normal number - Wikipedia

    en.wikipedia.org/wiki/Normal_number

    For bases r and s with log r / log s rational (so that r = b m and s = b n) every number normal in base r is normal in base s. For bases r and s with log r / log s irrational, there are uncountably many numbers normal in each base but not the other. [10] A disjunctive sequence is a sequence in which every finite string appears. A normal ...

  6. Significant figures - Wikipedia

    en.wikipedia.org/wiki/Significant_figures

    The base-10 logarithm of a normalized number (i.e., a × 10 b with 1 ≤ a < 10 and b as an integer), is rounded such that its decimal part (called mantissa) has as many significant figures as the significant figures in the normalized number. log 10 (3.000 × 10 4) = log 10 (10 4) + log 10 (3.000) = 4.000000...

  7. Base unit of measurement - Wikipedia

    en.wikipedia.org/wiki/Base_unit_of_measurement

    A base unit of measurement (also referred to as a base unit or fundamental unit) is a unit of measurement adopted for a base quantity.A base quantity is one of a conventionally chosen subset of physical quantities, where no quantity in the subset can be expressed in terms of the others.

  8. Metric system - Wikipedia

    en.wikipedia.org/wiki/Metric_system

    For example, the base unit of length is the metre, and distances much longer or much shorter than 1 metre are measured in units that are powers of 10 times a metre. This is unlike older systems of units in which the ratio between the units for longer and shorter distances varied: there are 12 inches in a foot, but the number of 5,280 feet in a ...

  9. Exponentiation - Wikipedia

    en.wikipedia.org/wiki/Exponentiation

    Exponentiation with base 10 is used in scientific notation to denote large or small numbers. For instance, 299 792 458 m/s (the speed of light in vacuum, in metres per second) can be written as 2.997 924 58 × 10 8 m/s and then approximated as 2.998 × 10 8 m/s. SI prefixes based on powers of 10 are also used to
