Examples
Precedence example
2 + 3 × 4² = 2 + 3 × 16 = 50 — the exponent applies before multiplication.
Parentheses example
(2 + 3) × 4 = 20 — grouping changes the order of evaluation.
Common questions
Does it support trig and logs?
Yes — sin, cos, tan, log, ln and roots are on the keypad. Switch DEG/RAD for angles before evaluating trig functions.
Can I reuse the previous answer?
Yes — ANS inserts the last result into the next expression, so you can chain calculations.
Keyboard shortcuts?
Numbers, operators and Enter (=) all work directly from your keyboard; Escape clears the display.
