Mathematical Formula & Logic

Result = (Numerator1 * Denominator2 +/- Numerator2 * Denominator1) / (Denominator1 * Denominator2)
Variable Glossary
Numerator The top number of a fraction showing how many equal parts are selected
Denominator The bottom number of a fraction showing how many total parts divide the unit

Step-by-Step Worked Calculation

Scenario: Adding 1/2 and 1/3

Calculate the sum of half and one-third shares.

1

Step 1: Identify denominators 2 and 3. Find the lowest common multiple (LCM), which is 6.

2

Step 2: Convert fractions: 1/2 becomes 3/6, and 1/3 becomes 2/6.

3

Step 3: Add numerators: 3 + 2 = 5. Denominator remains 6.

4

Step 4: Final simplified result is 5/6 (approx 0.833).

Historical Background

Mathematics has evolved over thousands of years, from ancient Babylonian clay tablets and Egyptian papyri to Greek formal proofs by Euclid and Archimedes. The development of algebra by Persian mathematician al-Khwarizmi in the 9th century and the invention of calculus by Newton and Leibniz in the 17th century laid the groundwork for modern computation. Fraction Calculator continues this tradition by making mathematical operations accessible through digital technology.
