Number three is wrong. Technically, that is, pedantically speaking **there isn’t a coefficient**.

**A coefficient** is a numerical or constant quantity placed before and multiplying the **variable** in an algebraic expression. There is no variable here, so **there is no coefficient**.

(Oh, and it’s not a physical constant either. There is no reference to any kind of physical relation.)

P.S. If you need a string of curses, I can provide them for you ... in several languages.

Technically, that IS the nomenclature or definitions used for the parts of a number in scientific notation:

https://www.shmoop.com/basic-operations/scientific-notation.html

...and from Wikipedia:

In mathematics, a coefficient is a multiplicative factor in some term of a polynomial, a series, or any expression

So people DO understand that the 5.28 portion is known as the coefficient.

**A coefficient** is a multiplicative factor in some term of a polynomial, a series, or any expression. Note that all the examples for coefficients precede variables in wikipedia.org/wiki/Coefficient,. They are sometimes depicted in non-italicized boldfaced letters defined as constants for given equations, but they always precede variables. **Note that no example is listed for use without the subsequent variable, even in the case of a series.**

The only official exception to this is in **physics**, where it’s used as a constant for conversion in an equation, where it usually precedes a variable.

The example in shmoop.com (which sounds like a pet name for a lover) though understandable, is, in fact, arbitrary. The *unshmoopified*, formal and official name for this portion of the expression is** mantissa. **

**Yes,** **shmoopy, it’s easy to understand that portion could be called a coefficient. I think it’s a great alternative name. However, this post is a pedantic, hair-splitting, mathematical definition, which does not allow for casual vocabulary. **

**...Though there is always some room for sweet-talk. **
