Credentials: PhD Mathematics, M.Sc Statistics
Dr. Sharma holds a PhD in Applied Mathematics from IIT Delhi and specializes in computational algorithms. She reviews all scientific and mathematical calculators for accuracy using international IEEE standards.
This calculator has been verified for accuracy by our team of experts and is reviewed monthly to ensure compliance with current regulations and industry standards.
After years of teaching mathematics and seeing students struggle with clunky scientific calculators, I wanted to build something better—a calculator that's not just powerful, but actually enjoyable to use.
What makes this different: Beyond the standard scientific functions (trigonometry, logarithms, exponentials), we've added features students and professionals actually need: automatic history tracking (never lose a calculation again), multiple themes for comfortable viewing, flexible layouts for any screen size, and helpful tooltips explaining each function.
Educational focus: Each function includes clear explanations and examples. Whether you're learning calculus, working on physics problems, or doing engineering calculations, the interface guides you through complex operations step-by-step.
Verified for accuracy using IEEE mathematical standards. All calculations run locally in your browser—no data is ever transmitted.
A scientific calculator is an advanced computational tool that performs complex mathematical operations beyond basic arithmetic—including trigonometry (sin, cos, tan), logarithms (log, ln), exponentials (e^x, 10^x), factorials, roots, and hyperbolic functions.
Our online calculator includes 30+ mathematical functions, supports both radians and degrees, automatically saves your last 50 calculations, and works on any device without downloads or installation.
Using our free scientific calculator online is simple and intuitive. Here's a step-by-step guide:
Click number buttons (0-9) to input values, use the decimal point (.) for fractions, and click operators (+, -, ×, ÷) to perform calculations. Press the equals button (=) or Enter key to see results.
Store values for later use with memory buttons: MS (Memory Store), MR (Memory Recall), M+ (Memory Add), M- (Memory Subtract), and MC (Memory Clear). Perfect for multi-step calculations.
Speed up calculations with keyboard: type numbers directly, use +, -, *, / for operations, Enter for equals, Escape to clear, and Backspace to delete.
Access your last 50 calculations in a beautiful modal overlay by clicking the History icon. Every calculation including functions (sin, sqrt, log), arithmetic operations, and constants (π, e) is automatically saved with timestamps. Click any previous calculation to reuse the result. Export your calculations as JSON or CSV for documentation, copy results with one click, or share calculations via URL to collaborate with colleagues and classmates worldwide.
Personalize your experience with 5 beautiful dark themes (Default Dark, Midnight Blue, Ocean Blue, Forest Green, Sunset Orange) or switch to Light mode. The calculator automatically adapts to time of day - enabling dark mode from 6 PM to 6 AM for comfortable evening use. Choose from 5 layout options: Compact (1:1, default), Medium (3:2), Standard (2:1), Large (3:1), or Extra Wide (4:1) to match your screen size and personal preference. Toggle dark/light mode anytime with the sun/moon icon.
Hover over any scientific function button to see a helpful tooltip explaining what it does. Perfect for learning new functions or refreshing your memory on advanced operations.
