What Is Decomposition in Mathematics?

In mathematics, decomposition means breaking a number, fraction, or algebraic expression into simpler components that are easier to analyze or work with.

Examples include:

  • Writing 345 as 300 + 40 + 5 (expanded form)
  • Simplifying 12/18 to 2/3
  • Factoring x² + 5x + 6 into (x + 2)(x + 3)
  • Expressing 60 as 2² × 3 × 5 (prime factorization)

Decomposition helps improve mathematical understanding and problem-solving efficiency.

How to Use the Decomposition Calculator

Using this calculator is simple and intuitive.

Step 1: Choose Decomposition Type

Select from:

  • Number
  • Fraction
  • Polynomial
  • Prime Factorization

The form automatically updates based on your selection.

How to Decompose a Number

  1. Enter the number.
  2. Select a method:
    • Place Value
    • Expanded Form
    • Additive
    • Multiplicative
  3. Click “Calculate.”

Example:

If you enter 456 and choose Expanded Form:

Result:
456 = 400 + 50 + 6

If you choose Place Value:
456 = 4 × 10² + 5 × 10¹ + 6 × 10⁰

You also get step-by-step explanations and verification.

How to Simplify a Fraction

  1. Enter numerator and denominator.
  2. Click “Calculate.”

The tool:

  • Finds the Greatest Common Divisor (GCD)
  • Divides numerator and denominator by GCD
  • Displays simplified fraction
  • Shows decimal value

Example:

Input:
12 / 18

Output:
2 / 3
Decimal: 0.6667
Step-by-step: GCD = 6

How to Factor a Polynomial

  1. Select degree (Quadratic, Cubic, Quartic).
  2. Enter coefficients.
  3. Click “Calculate.”

For quadratics:

The tool:

  • Calculates the discriminant
  • Determines real or complex roots
  • Displays factored form

Example:

Input:
x² + 5x + 6

Output:
(x – (-2))(x – (-3))
Roots: x = -2, -3

If the discriminant is negative, the tool informs you that real factorization is not possible.

How to Perform Prime Factorization

  1. Enter a positive integer (greater than 1).
  2. Choose format:
    • Standard
    • Exponential
    • Factor List
  3. Click “Calculate.”

Example:

Input:
60

Standard:
2 × 2 × 3 × 5

Exponential:
2² × 3 × 5

Additional info:
Number of prime factors: 4

The calculator divides by the smallest prime repeatedly to ensure accurate results.
