How this works
- Order: brackets → exponents → × ÷ → + −. So
2 + 3 * 4 = 14.
- Exponents are right-associative:
2^3^2 = 512, not 64.
- Unary minus binds loosely:
-3^2 = −9. Use (-3)^2 for 9.
- Enter saves the result to history, Esc clears the field.
How do I calculate a square root?
Use sqrt(x), so sqrt(144) gives 12. You can also raise to the power 0.5. For a cube root, use x^(1/3).
Why does sin(30) differ from my phone?
Almost certainly an angle-mode mismatch. In degrees sin(30) is 0.5; in radians about −0.988. Switch the degrees/radians selector.
What is the difference between log and ln?
log is base 10, so log(1000) is 3. ln is base e, so ln(e) is 1. Scientific and financial formulas usually mean ln.
