  2. Scientific notation - Wikipedia

    en.wikipedia.org/wiki/Scientific_notation

    Converting a number from scientific notation to decimal notation, first remove the × 10 n on the end, then shift the decimal separator n digits to the right (positive n) or left (negative n). The number 1.2304 × 10 6 would have its decimal separator shifted 6 digits to the right and become 1,230,400 , while −4.0321 × 10 −3 would have its ...

    en.wikipedia.org/wiki/Mathematics

    Mathematical notation is widely used in science and engineering for representing complex concepts and properties in a concise, unambiguous, and accurate way. This notation consists of symbols used for representing operations, unspecified numbers, relations and any other mathematical objects, and then assembling them into expressions and ...

  4. 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.
