= Signomial
{wiki=Signomial}
A signomial is a mathematical expression that is similar to a polynomial, but it allows for terms with both positive and negative coefficients, while also being defined over real or complex numbers. In a signomial, each term (called a monomial) can be represented as a product of a coefficient and one or more variables raised to a power. However, unlike polynomials, signomials can include terms with negative coefficients, which means that they can have terms that affect the overall sign of the expression.
