What you can type

Examples of what the calculator understands
Powers	2^10 · 3² · 10⁻²
Roots	√16 · ∛27 · root(32, 5)
Factorial, percent	5! · 15%15% means 15 ÷ 100
Multiply without ×	2π · 3(4) · 2sin(30)
Logs	ln(e) · log(100) · log2(8)ln is base e, log is base 10
Counting	nCr(5, 2) · nPr(5, 2)Choices and arrangements
Previous answer	Ans × 2

Keyboard: type straight into the box. Enter works out the answer, Esc clears, ↑ ↓ bring back earlier lines.

How it’s calculated: brackets first, then powers and roots, then × and ÷ from left to right, then + and −. Multiplying without a sign (2π) counts as ×. Answers are rounded to 12 significant digits, so 0.1 + 0.2 shows 0.3.
