This is a simple online basic calculator with AI that makes solving basic math problems faster and easier. You can use it for addition, subtraction, multiplication, and division — just like a standard handheld calculator.
What makes our free basic calculator better? It also supports square root, percentage, pi (π), exponents, powers, and even rounding. Whether you're a student solving homework problems or a professional doing quick calculations, our AI-powered calculator is built for everyday use.
You can use the calculator with your mouse, keyboard, number pad, or touch — whichever suits your device best. No app download, no sign-up — just open and calculate.
Start using the best free AI basic calculator online now and make your daily calculations quicker and smarter.
While our free Basic Calculator online tool is perfect for quick, everyday calculations, if you're looking to solve more complex math problems, our powerful Scientific Calculator is here to help with advanced functions like trigonometry, logarithms, and more.
Perform simple arithmetic calculations like Addition (+), Subtraction (-), Multiplication (×), and Division (÷). These are the foundational operations for everyday calculations.
This button helps you square any number. For example, pressing 5 followed by x² gives you 25. It’s useful when working with powers in mathematics.
The square root function gives you the square root of a number. For instance, √9 results in 3. This function is essential for advanced math or for solving quadratic equations.
Converting a number into a percentage is easy with the % button. For example, pressing 50 followed by % gives you 0.5, which is useful in finding discounts, taxes, or interest rates.
You can change the sign of the current number. If the number is positive, it becomes negative, and vice versa. For example, pressing +/- on a 5 will convert it into -5.
The memory function allows you to store numbers temporarily. For example, pressing MC clears memory, MR recalls memory, M+ adds to memory, and M- subtracts from memory. This is useful for complex calculations that require storing interim results.
Function | Description |
---|---|
AC (All Clear) | Clears all input and resets the calculator. It’s useful when you want to start over or when calculations go wrong. |
Square Root (√) | Calculates the square root of the number you input. For example, √25 will give you 5. |
Square (x²) | Squares the number you input. For instance, pressing 4 followed by x² will result in 16. |
Percentage (%) | Converts a number into a percentage. For example, pressing 200 followed by % will give you 2 (200 ÷ 100). |
+/- (Toggle Sign) | Changes the sign of the number, making it positive if it’s negative and vice versa. For example, pressing +/- on 7 will turn it into -7. |
If you want to add 50 and 30, press 50, then +, then 30 and finally press =. The result will be 80.
For subtracting 30 from 70, press 70, then -, then 30 and press =. The result will be 40.
Multiply 12 by 3 by pressing 12, then ×, and then 3, followed by =. The result will be 36.
To divide 36 by 6, press 36, then ÷, then 6, and press =. The result will be 6.
Press 5 followed by x² to get 25. This is useful for calculating powers in math.
Press √9 to get 3. This is essential for advanced mathematics like solving quadratic equations.
Tip | Description |
---|---|
Double-Check Operations | Ensure accurate results by double-checking each operation before pressing the equals button (=) to avoid mistakes. |
Use AC Frequently | Use the AC button often when switching between calculations or if you encounter any errors. This will keep things clean. |
Break Down Complex Calculations | When working with larger numbers or complicated equations, break them into smaller steps for better accuracy. |
Use +/- When Needed | When dealing with both positive and negative numbers, use the +/- function to quickly switch between signs. |
