For example: $\displaystyle 3s^2$ I might say in words "the coefficient of s squared is 3", but if I'm writing it down, I can't say: $\displaystyle s^2=3$. Therefore, is there a symbol that I can use to express a coefficient? Kind Regards Edward

If there are a small number of constant coefficients, you might use "a", "b", "c", etc., for them.
