An accurate and easy-to-use tool for subtracting one number from another. Get precise results, a history of your calculations, and copy the difference instantly.
The formula for subtraction finds the difference between two numbers:
Difference = Minuend - Subtrahend
Subtraction is the inverse of addition, meaning that `a - b` is equivalent to `a + (-b)`.
The Subtraction Calculator is a precise and user-friendly tool designed for anyone who needs to find the difference between two numbers quickly and accurately. As the inverse operation of addition, subtraction is a fundamental arithmetic function used in countless daily scenarios, from managing finances to scientific analysis. This calculator ensures that these operations are performed flawlessly, eliminating the risk of manual errors and providing features that enhance productivity. Our tool is built to be fast, reliable, and accessible on any device, making it a go-to resource for students, professionals, and anyone in need of a quick calculation.
A key focus of this Subtraction Calculator is its adherence to the strict mathematical properties of subtraction. Unlike addition, subtraction is non-commutative, meaning the order of the numbers is crucial. The logic of our calculator rigorously enforces this rule, ensuring that `Minuend - Subtrahend` is calculated exactly as entered. It is also non-associative, a principle that governs how expressions with multiple subtractions are evaluated. By focusing on a clean two-input system, our calculator simplifies the process and prevents ambiguity. The interface clearly labels the 'Minuend' (the number being subtracted from) and the 'Subtrahend' (the number being subtracted) to guide the user and ensure correct input.
The Subtraction Calculator offers several features that make it more than just a simple calculation engine. The calculation history automatically logs each operation with a timestamp, allowing users to review their recent work without starting over. This is invaluable for tasks that involve a series of related subtractions. Additionally, the one-click "Copy Result" function streamlines any workflow that requires transferring results to other documents or applications. For those interested in the mathematical theory behind this tool, resources like Wikipedia's page on Subtraction provide in-depth information. Educational platforms such as Khan Academy offer excellent tutorials on basic arithmetic.
Ultimately, the Subtraction Calculator is designed for efficiency and accuracy. It handles integers, decimals, and negative numbers with ease, applying the correct sign rules for every scenario. Whether you're balancing a checkbook, calculating a discount, or solving a homework problem, this tool provides the precision you need. The responsive design ensures a seamless experience on desktops, tablets, and smartphones. By stripping away unnecessary complexities, the Subtraction Calculator delivers on its core promise: to provide a reliable and easy-to-use solution for all your subtraction needs.

Subtraction is non-commutative, which means that A - B is not the same as B - A. The first number (Minuend) is the one you are subtracting from, and the second (Subtrahend) is the number being subtracted. The calculator respects this order to ensure a correct result.
Yes, it fully supports negative numbers for both inputs. For example, you can calculate -10 - (-5), which correctly results in -5.
Absolutely. You can enter decimal values (e.g., 25.5 - 10.2) in both input fields to get a precise decimal result.
The history log keeps track of all calculations you perform during your current session on the page. If you refresh or close the page, the history will be cleared.
Yes, the Subtraction Calculator is completely free. There are no hidden fees or subscriptions required to use its full functionality.
