A number used to multiply a variable

Use instead: Something used to multiply the concerned variable

Coefficient

A number used to multiply a variable.

Example: 6z means 6 times z, and "z" is a variable, so 6 is a coefficient.

Sometimes a letter stands in for the number.

Example: In ax² + bx + c, "x" is a variable, and "a" and "b" are coefficients.

Let me know if you feel it can be improved.

Write the definition you like and whomever disagrees, kill them.

The R^whatever does not seem like too much a problem either, considering it's the R that matters.

]]>What does everyone think about that?

To be honest, it isn't too big of an issue. Such terminology discrepancies occur all the time and it is just a matter of convention (e.g. in the UK they use R^d instead of R^n like here in the US in real analysis).

However, 1 is not a coefficient - it is a constant.

In 2x + 1x^2 though, both 2 and 1 are coefficients.
