Polynomial Calculator

Add or subtract polynomials up to degree 10 step-by-step. Enter coefficients for each term.

📘 About the Polynomial Calculator

This calculator allows you to add or subtract polynomials up to degree 10. Enter the degree and coefficients for two polynomials P(x) and Q(x), select the operation, and the calculator computes the resulting polynomial instantly with a clear step-by-step display.

🔢 Enter Polynomials of Any Degree

Input your polynomials easily:

  • Choose the degree for P(x) and Q(x) (0–10)
  • Provide coefficients for each term from highest to lowest power
  • The calculator automatically generates the polynomial expressions dynamically

This makes it beginner-friendly and flexible for any polynomial within the supported degree range.

➕ Add or Subtract Polynomials

The calculator supports both operations:

  • Add P(x) + Q(x) to get the combined polynomial
  • Subtract P(x) − Q(x) for differences
  • Automatically aligns terms with the same power for correct calculation

The resulting polynomial is displayed in standard form with proper formatting for powers and coefficients.

✍️ Clear Formula Display

Learn how your input coefficients form polynomials:

  • Each input dynamically updates the polynomial formula
  • Shows coefficients with subscripts and powers with superscripts
  • Helps visualize the polynomial structure as you type

This feature makes it educational and helps beginners understand polynomial expressions.

⚡ Instant Results & Beginner Friendly

Get immediate feedback as you type:

  • Results update in real-time with no manual calculation
  • Displays P(x), Q(x), and the resulting polynomial clearly
  • Perfect for homework, practice, or learning polynomial operations

⚙️ How the Calculator Works

1. Enter the degree and coefficients for P(x) and Q(x).
2. Select the operation: Add or Subtract.
3. The calculator aligns coefficients of like powers and performs the operation term by term.
4. The resulting polynomial is displayed dynamically with proper formatting using subscripts for coefficients and superscripts for powers.
5. Input validation ensures numbers are valid and prevents errors from missing coefficients.

This allows students and beginners to explore polynomial operations and understand how addition and subtraction affect coefficients and powers.

📌 Example

Suppose you have polynomials:

P(x) = 2x³ + 3x² − x + 5
Q(x) = x³ − 2x² + 4x − 1

The calculator computes:

P(x) + Q(x) = 3x³ + x² + 3x + 4
P(x) − Q(x) = x³ + 5x² − 5x + 6

Coefficients and resulting polynomial are displayed instantly, updating as you modify inputs.
