About the Math Solver
Math Solver is a free, browser-based scientific calculator for everyday and exam-level calculations. It runs entirely on your device - nothing you type is sent anywhere, so it works instantly and keeps your calculations private.
What you can calculate
- Basic arithmetic - addition, subtraction, multiplication, division with correct order of operations
- Trigonometry - sin, cos and tan, with a Degree/Radian toggle so you can switch modes depending on the problem
- Logarithms - log (base 10) and ln (natural log)
- Powers and roots - square (x²), cube (x³), square root (√x), and any custom power using the ^ key
- Factorials - x! for combinatorics and probability problems
- Reciprocal - 1/x for quick inverse calculations
- Constants - π and e available at a tap
- Memory functions - MC, MR, MS and M+ to store a running value across multiple calculations
How to use it
- Tap the number keys to enter your value.
- Use +, −, ×, ÷ or ^ for operations, and ( ) to group parts of a longer expression.
- For trigonometry, set DEG or RAD first, then tap sin, cos or tan followed by your angle.
- Tap = to see the result, or ⌫ to correct a mistake without clearing everything.
- Tap C any time to start a fresh calculation.
