Instant display of subtraction results
You can perform subtraction in just 3 steps:
Subtraction is used in various situations in daily life:
Perfect for elementary arithmetic learning, mental calculation practice, and building math fundamentals. Example: 10 - 3 = 7, 25 - 8 = 17. Visual feedback deepens understanding.
Calculate change when paying or the difference between budget and actual expenses. Example: $100.00 - $38.50 = Change $61.50.
Calculate account balance, budget remainder, inventory remaining, etc. Example: Monthly budget $5,000 - Expenses $3,250 = Remainder $1,750.
Calculate differences such as month-over-month or year-over-year. Example: This month's sales $13,500 - Last month's sales $12,000 = Increase $1,500.
Calculate score differences in tests or games, differences from goals. Example: Target score 90 - Actual score 75 = Shortfall 15.
Subtraction is a basic arithmetic operation that finds the difference by taking one number away from another. In mathematics, it is represented by the "−" symbol and is one of the most fundamental operations.
Subtraction has the following important mathematical properties:
a - b ≠ b - a (generally) Example: 5 - 3 = 2, but 3 - 5 = -2
(a - b) - c ≠ a - (b - c) (generally) Example: (10 - 5) - 2 = 3, but 10 - (5 - 2) = 7
a - 0 = a Example: 7 - 0 = 7
Common examples of subtraction:
Results are displayed as you type. No need to press a button - you get instant answers.
The calculation and result are displayed simultaneously, making it easier for learners to understand the calculation process.
Prevents manual calculation mistakes and guarantees accurate results. Especially powerful for large numbers or decimal calculations.
Use on any device including PC, smartphone, and tablet. Access anytime with just an internet connection.
You can also enter negative numbers. Example: 5 - (-3) = 8 (subtracting a negative is like adding), -5 - 3 = -8 (subtracting more from negative).
Accurately calculates numbers with decimal points. Example: 5.5 - 2.25 = 3.25. This tool uses a high-precision calculation library to minimize floating-point errors.
Clicking the "Clear" button resets all input fields and results, returning focus to the first input field.
Move between input fields using the Tab key. You can also fine-tune numbers with arrow keys (↑↓).
Subtracting a negative number is equivalent to adding its absolute value. Example: 10 - (-5) = 15, -3 - (-2) = -1. Mathematically, it's the same principle as "minus times minus equals plus."
Yes, this tool supports decimal subtraction. Example: 5.5 - 2.25 = 3.25. It uses a high-precision calculation library to minimize floating-point errors.
This tool uses a high-precision calculation library (Decimal.js) that provides higher precision than standard floating-point arithmetic. You get accurate results even with large numbers or decimals.
No, all calculations are performed within your browser and no data is sent to the server. Your input numbers are not stored at all, and your privacy is fully protected.
Yes, when the subtrahend is larger than the minuend, the result will be negative. Example: 5 - 10 = -5.
