Adding and Subtracting Polynomials Calculator

Adding and subtracting calculator is a free online tool to compute the summation of the difference of two polynomial equations. To recall, a polynomial equation is an equation which is formed with variables, exponents and coefficients.

How to Use the Addition and Subtraction Calculator?

This calculator for addition and subtraction is extremely easy to use and can quickly compute the sum or difference of any two polynomial equations. To use the calculator, follow the steps given below:

  • Step 1: Enter the first polynomial in the first input box.
  • Step 2: Enter the second polynomial in the second input box.
  • Step 3: Choose the type of operation as “addition” or “subtraction”.
  • Step 4: Click on the “Calculate” button.

How to Add and Subtract Polynomials?

To add or subtract two polynomials, add or subtract the coefficients of variables having the same power. For example, to add 3x2 + 2x + 4 and 2x2 + x + 1, first, add the coefficients of “x2”, then add coefficient of “x” and finally add the remaining terms. So, for this case, the solution will be (3 + 2)x2 + (2 + 1)x + (4 + 1) = 5x2 + 3x + 5

Frequently Asked Questions on Adding and Subtracting Polynomials


What Are Polynomials?

Polynomials are expressions which are composed of many terms. The term “poly” means many and “nomial” means terms. Know more about polynomials here-


How to Add Polynomials Vertically?

To add polynomials vertically, remove all the brackets and parentheses by solving and simplifying them. Then add the like terms i.e. add the constants of variables having the same power.


What is the Difference Between Adding and Subtracting Polynomials?

In addition of polynomials, the like terms are added while in subtraction, the like terms are subtracted. Remember, the basic algebra concept that the sign after addition or subtraction will always be of the variable having more value.
