1. What is Fraction Subtraction?

Fraction subtraction is a mathematical operation that finds the difference between two fractions. To subtract fractions, they must have a common denominator, which is achieved by finding the least common multiple of the denominators.

2. How Does the Calculator Work?

The calculator uses the standard fraction subtraction formula:

\[ \frac{a}{b} - \frac{c}{d} = \frac{a \times d - b \times c}{b \times d} \]

Where:

\( a \) — Numerator of first fraction
\( b \) — Denominator of first fraction
\( c \) — Numerator of second fraction
\( d \) — Denominator of second fraction

Explanation: The calculator first finds a common denominator by multiplying the denominators, then subtracts the numerators accordingly, and finally simplifies the result if possible.

3. Importance of Fraction Subtraction

Details: Fraction subtraction is fundamental in mathematics and has applications in various fields including engineering, physics, and everyday measurements. Understanding this operation is essential for solving complex mathematical problems.

4. Using the Calculator

Tips: Enter the numerators and denominators of both fractions. Denominators must be positive integers. The calculator will display the result in both unsimplified and simplified forms (if simplification is possible).

5. Frequently Asked Questions (FAQ)

Q1: Can I subtract fractions with different denominators?
A: Yes, the calculator automatically finds a common denominator by multiplying the denominators together.

Q2: What if my result is an improper fraction?
A: The calculator shows the result as-is, including improper fractions. You may convert it to a mixed number if desired.

Q3: How does the simplification work?
A: The calculator finds the greatest common divisor (GCD) of the numerator and denominator and divides both by this number.

Q4: What if I enter negative numbers?
A: Negative numerators are allowed and will be handled correctly. Denominators must remain positive.

Q5: Can I subtract whole numbers with this calculator?
A: Yes, whole numbers can be entered as fractions with denominator 1 (e.g., 5 = 5/1).
