Scientific Calculator Online

A calculator for when a basic four-function one isn't enough — trigonometric functions, logarithms, exponents, roots, and the usual scientific-calculator memory functions, all in a browser tab instead of a physical device or a phone app.

What it supports

• Basic arithmetic plus order-of-operations handling
• Trigonometric functions (sin, cos, tan and their inverses), in both degrees and radians
• Logarithms (base 10 and natural log)
• Exponents and roots, including nth roots
• Constants like π and e
• Memory functions (store, recall, clear)

How to use it

Click the buttons or type directly using your keyboard — both work. Switch between degree and radian mode depending on what your calculation needs; this is the most common source of wrong trig results, so double check it's set correctly before trusting an answer that looks off.

FAQ

Degrees or radians — which should I use? Most everyday and geometry problems use degrees. Radians are the standard in calculus and most programming math libraries. Check which one your source material or assignment expects.

Does it handle order of operations correctly? Yes, standard mathematical precedence is followed (parentheses, exponents, multiplication/division, addition/subtraction).

Can I use it for financial or statistical calculations? It covers general scientific/trig/log functions. For statistics specifically, the Statistics Calculator is a better fit; for loans, see the dedicated loan calculator tools.
