Free tool
Scientific calculator, type or tap.
Type a sum with your keyboard or tap the keys, and the answer shows as you go; press Enter or = to keep it. Sine, cosine and tangent in degrees or radians, powers and roots, natural and base-10 logs, factorials, pi and e, brackets, memory and a history you can click to reuse. "ans" holds the last answer. No eval, no ads, nothing sent anywhere.
History
Keyboard: type the sum, Enter for =, Esc to clear. Implied multiplication works: 2pi, 3(4+1), 2x. sin30 means sin(30).

Click any past line to use it again; M+, M−, MR and MC work as on a desk calculator.
Questions
Good to know.
How do I switch between degrees and radians?
Press DEG. It shows RAD when radians are on.
How do I type powers and roots?
Use ^ for powers (2^10), the x² key, sqrt( for square roots and cbrt( for cube roots.
What does ans mean?
The last answer you kept with =.
Is the order of operations correct?
Yes: brackets, powers, then multiply and divide, then add and subtract. -2^2 is -4.
Does it keep my history?
Yes, in this browser, until you clear it.
