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 ...

4. Standard notation for an equivalence relation. 5. In probability and statistics, may specify the probability distribution of a random variable. For example, (,) means that the distribution of the random variable X is standard normal. [2] 6. Notation for proportionality.
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).
Scientific notation (for example 1 × 10 10), or its engineering notation variant (for example 10 × 10 9), or the computing variant E notation (for example 1e10). This is the most common practice among scientists and mathematicians. SI metric prefixes. For example, giga for 10 9 and tera for 10 12 can give gigawatt (10 9 W) and terawatt (10 12 ...

Roman numerals: The numeral system of ancient Rome, still occasionally used today, mostly in situations that do not require arithmetic operations. Tally marks: Usually used for counting things that increase by small amounts and do not change very quickly.
