Getting Started

Enter any two values (factors, product, or sum) and the calculator will find the missing values automatically.

Example Problems

Example 1: Both factors given

Given: Factor A = 3, Factor B = 4

Solution:

• Product = 3 × 4 = 12

• Sum = 3 + 4 = 7

Diamond: Top = 12, Left = 3, Right = 4, Bottom = 7

Example 2: One factor and sum given

Given: Factor A = 6, Sum = 11

Solution:

• Factor B = Sum - Factor A = 11 - 6 = 5

• Product = 6 × 5 = 30

Diamond: Top = 30, Left = 6, Right = 5, Bottom = 11

Example 3: Product and sum given

Given: Product = 12, Sum = 7

Solution:

• Find factors of 12: (1,12), (2,6), (3,4), (-1,-12), (-2,-6), (-3,-4)

• Check which pair sums to 7: 3 + 4 = 7 ✓

• Therefore: Factor A = 3, Factor B = 4

Diamond: Top = 12, Left = 3, Right = 4, Bottom = 7

Diamond Problem Types

Case 1: Both Factors

Calculate product and sum from two given factors

Case 2: One Factor + Sum/Product

Find missing factor using basic arithmetic

Case 3: Product + Sum

Factor the product to find pairs that sum correctly

Understanding Diamond Problems

What is a Diamond Problem?

A diamond problem is a visual method for finding relationships between four numbers: two factors and their product and sum. The diamond shape helps organize these relationships in an intuitive way.

Diamond Layout

  • Top: Product of the two factors
  • Left & Right: The two factors
  • Bottom: Sum of the two factors

Applications

Factoring Quadratics:

x² + 7x + 12 = (x + ?)(x + ?)

Find numbers that multiply to 12 and add to 7

Problem-Solving Strategy

  • List factor pairs of the product
  • Test which pair gives the correct sum
  • Consider both positive and negative factors
  • Verify your solution in the diamond

Connection to Quadratic Factoring

Standard Form

ax² + bx + c

Find factors of c that sum to b

Factored Form

(x + m)(x + n)

Where m × n = c and m + n = b
