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 ...
The rule that multiplication has precedence over addition was incorporated into the development of algebraic notation in the 1600s, since the distributive property implies this as a natural hierarchy. As recently as the 1920s, the historian of mathematics, Florian Cajori, identifies disagreement about whether multiplication should have ...
In mathematics, Knuth's up-arrow notation is a method of notation for very large integers, introduced by Donald Knuth in 1976. [ 1 ] In his 1947 paper, [ 2 ] R. L. Goodstein introduced the specific sequence of operations that are now called hyperoperations .
That is, the multiplication rule implies the definition = ... Exponentiation with base 10 is used in scientific notation to denote large or small numbers.
Scientific notation is a way of writing numbers of very large and very small sizes compactly when precision is less important. A number written in scientific notation has a significand (sometime called a mantissa) multiplied by a power of ten. Sometimes written in the form: m × 10 n. Or more compactly as: 10 n
A binary prefix indicates multiplication by a power of two. The tenth power of 2 (2 10 ) has the value 1024 , which is close to 1000 . This has prompted the use of the metric prefixes kilo , mega , and giga to also denote the powers of 1024 which is common in information technology with the unit of digital information, the byte .

For a number written in scientific notation, this logarithmic rounding scale requires rounding up to the next power of ten when the multiplier is greater than the square root of ten (about 3.162). For example, the nearest order of magnitude for 1.7 × 10 8 is 8, whereas the nearest order of magnitude for 3.7 × 10 8 is 9.
