🚀 Pro Tips

Make sure you are in the correct angle mode (Degrees vs Radians) for trig functions.
Natural log (ln) uses base e ≈ 2.71828. Log (log) uses base 10.
Use brackets to control order of operations: 2 + 3 × 4 = 14, but (2+3) × 4 = 20.
For very large or very small numbers, scientific notation is used automatically (e.g. 1e-10).

Frequently Asked Questions

What is the difference between Degrees and Radians?+
Degrees split a full circle into 360°. Radians use π (≈3.14159) for a half circle. Radians are used in higher mathematics and physics; degrees are used in everyday geometry.
What does the modulo (mod) function do?+
Modulo returns the remainder of a division. Example: 17 mod 5 = 2 (because 17 = 5×3 + 2). It is used extensively in programming.
