How to use this calculator

Click "Open Calculator" to start. Type numbers and operators, or use the on-screen keys for trig, logs, roots, powers, and factorials. Toggle Degrees/Radians before using trig functions. Press "2nd" to unlock inverse trig (sin⁻¹, cos⁻¹, tan⁻¹) and inverse log/root functions (10ˣ, eˣ, x²). Press "=" to evaluate, and check "History" for your last calculations — click any entry to reuse it.

What functions are supported?

sin/sin⁻¹, cos/cos⁻¹, tan/tan⁻¹, log/10ˣ, ln/eˣ, √/x², powers (x^y), factorial (n!), reciprocal (1/x), percentage (%), memory (MC/MR/M+/M−), constants π and e, and standard +, −, ×, ÷ with parentheses for order of operations.

How does memory work?

M+ adds the current result to memory, M− subtracts it, MR recalls the stored value into your expression, and MC clears it. An "M" badge appears next to the calculator title whenever memory holds a non-zero value.

Does my data leave my device?

No. All calculations run locally in your browser — nothing is uploaded or sent anywhere.
