Polynomial Subtraction Calculator is an online tool for algebraic arithmetic calculation programmed to perform polynomial subtraction between two set of given polynomials. A polynomial is a single term or a sum of terms containing variables with whole number exponents. The degree of a term in one variable is the exponent. The degree of a nonzero constant is 0. The degree of a polynomial is the highest degree of any term in the polynomial. A polynomial is written in descending order if the terms are written from highest degree to lowest degree. In Polynomial Addition only like terms can be subtracted. Like terms are terms with the same variables raised to the same exponents. When subtracting only the coefficient changes; the variable part stays the same. Polynomial calculations are applied in chemistry, physics, calculus, numerical analysis and advanced mathematics. So learning polynomials becomes essential to solve many problems. When it comes to perform polynomial subtraction, this calculator will support up to 5 degree polynomial and help you to calculate the resulting polynomial
