This mode supports complex expressions with parentheses and order of operations. Perfect for algebra, calculus, physics, and engineering calculations.

Programmer Mode

Designed for computer science professionals and students, this mode supports binary, octal, decimal, and hexadecimal calculations. Features include bitwise operations (AND, OR, XOR, NOT), bit shifting (<<, >>), and number base conversions. Essential for debugging code, understanding memory operations, and low-level programming tasks.

Graph Mode

Visualize mathematical functions with our interactive graphing tool. Plot multiple functions including trigonometric, logarithmic, exponential, and polynomial expressions. Use zoom controls to analyze specific regions of the graph. Perfect for understanding function behavior, finding roots, intersections, and visualizing mathematical concepts.

Statistics Mode

Perform statistical analysis on datasets including mean, median, standard deviation, variance, and regression calculations. Enter data points and instantly see comprehensive statistical results. Ideal for data analysis, research projects, quality control, and academic statistics courses.

Advanced Features

Memory Functions

Frequently Asked Questions

How do I switch between calculator modes?

Click on the mode tabs at the top of the calculator (Standard, Scientific, Programmer, Graph, or Statistics). The keypad will automatically update to show functions relevant to the selected mode. Your current calculation is preserved when switching between Standard and Scientific modes.

How do I use the graphing feature?

Switch to Graph mode, then enter your function using the keypad (e.g., sin(x), x^2, log(x)). Click the "Plot" button to generate the graph. Use the zoom controls to adjust the view, and click and drag to pan across the graph. Click "Save Graph" to download the image for reports or presentations.

What's the difference between log and ln?

"log" refers to the base-10 logarithm (common logarithm), while "ln" refers to the natural logarithm (base-e). For example, log(100) = 2 because 10² = 100, while ln(e) = 1 because e¹ = e. In scientific contexts, "ln" is more commonly used for natural phenomena and calculus.

How do I change between degrees and radians for trig functions?

In Scientific mode, click the DEG, RAD, or GRAD buttons to switch between angle modes. The display will briefly show your current mode (DEG, RAD, or GRAD). This setting affects all trigonometric calculations (sin, cos, tan). For example, sin(30) in DEG mode equals 0.5, but in RAD mode it equals -0.988.

How do memory functions work?

M+ adds the displayed value to memory, M- subtracts it from memory, MR recalls the stored value to the display, and MC clears the memory. The memory value is preserved between calculations and mode changes. A brief notification appears when memory operations are performed.

Can I use parentheses in calculations?

Yes! In Scientific mode, use the ( and ) buttons to create complex expressions with proper order of operations. For example: (2+3)*4 = 20, while 2+3*4 = 14. You can nest parentheses up to 10 levels deep for complex formulas.

How do I access scientific constants like π or e?

In Scientific mode, click the π or e buttons to insert these constants into your calculation. For other constants (φ, G, c, h, k), type their symbols directly in expressions or use the Constants menu if available. All constants are stored with maximum precision for accurate calculations.

Why does my calculation show "Error"?

This typically happens with invalid operations like division by zero, taking the square root of a negative number (in real mode), mismatched parentheses, or syntax errors in expressions. For trigonometric functions, extremely large values might cause errors. Check your input and try again with valid parameters.

How do I clear the calculation history?

The history automatically keeps the last 10 calculations. To clear it completely, refresh the page or use the "Clear History" option if available in the history panel menu. Note that history is not preserved between browser sessions for privacy reasons.

Can I use this calculator offline?

Yes! Once the page is fully loaded, all calculator functions work offline. For permanent offline access, save the entire webpage to your device (Ctrl+S or Cmd+S). The PDF documentation can also be downloaded for reference without an internet connection. All calculations are performed locally in your browser with no data sent to servers.

How do I plot multiple functions on the same graph?

In Graph mode, enter your first function and click "Plot". Then enter a second function and click "Plot" again. The calculator will overlay both functions on the same graph with different colors. You can plot up to 3 functions simultaneously for comparison. Use the "Reset View" button to start fresh.

What statistical functions are available?

In Statistics mode, you can calculate mean, median, standard deviation, variance, sum, minimum, and maximum values. Enter data points separated by commas (e.g., "5, 10, 15, 20"), then click the desired statistical function. The calculator also shows the number of data points and working capital for financial analysis.
