ABOUT THIS CALCULATOR

---

This Scientific Calculator gives you the power of a handheld scientific calc right in your browser, without the clutter. It supports everyday arithmetic plus functions you actually use in the field or in class: trig (sin, cos, tan in radians), powers, roots, logarithms (log and ln), and constants like π and e. The live display shows both the expression and the evaluated result as you type, so you can see mistakes immediately instead of waiting until the end of a long calculation.

Because it’s keyboard-friendly, it’s much faster to use than tapping numbers on a phone. You can type directly on your keyboard (numbers, +, -, *, /, parentheses, ^), hit Enter for equals, Backspace to delete, and Esc for AC. That makes it great for anyone doing repeated calculations: electricians, engineers, students, estimators, or anyone who just needs a clean, no-nonsense calc that understands more than basic math.

Click the buttons or type on your keyboard to build an expression. You can use:

• Basic operations: +, −, ×, ÷, parentheses ( ), and exponent ^
   
• Trig functions: sin( ), cos( ), tan( ) (all in radians)
   
• Roots and powers: √ for square root, or x^y for any power
   
• Logarithms: log( ) for base-10, ln( ) for natural log
   
• Constants: π and e
   

The top line shows the expression you’re building; the large line shows the result. As you add or remove terms, the result updates whenever the expression is valid. Press AC to clear everything, DEL to remove the last character, and = (or Enter) to “commit” the result back into the expression so you can continue calculating with it.

This tool is ideal for quick checks, homework, on-site math, and anything where you want more power than a basic calculator without opening a full CAS or spreadsheet.
