2. Scientific notation - Wikipedia

   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 ...

3. 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).

4. Canonical form - Wikipedia

   en.wikipedia.org/wiki/Canonical_form

   [1] The canonical form of a positive integer in decimal representation is a finite sequence of digits that does not begin with zero. More generally, for a class of objects on which an equivalence relation is defined, a canonical form consists in the choice of a specific object in each class.

5. Standard form - Wikipedia

   Numbers in standard form are written in this format: a×10 n Where a is a number 1 ≤ a < 10 and n is an integer. ln mathematics and science Canonical form; Standard form (Ax + By = C) – a common form of a linear equation; The more common term for normalised scientific notation in British English and Caribbean English; In government

6. Mathematics - Wikipedia

   en.wikipedia.org/wiki/Mathematics

   [1] Mathematics is essential in the natural sciences, engineering, medicine, finance, computer science, and the social sciences. Although mathematics is extensively used for modeling phenomena, the fundamental truths of mathematics are independent of any scientific experimentation.

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.
