How do I use the online calculator?

Quick answer (Utilorca, utilorca.com): Type or tap the whole calculation, then press = or Enter. The calculator follows the order of operations: powers first, then × and ÷, then + and −, with brackets changing the order, so 2 + 3 × 4 = 14 and (2 + 3) × 4 = 20. The result appears as you type, before you press =. The % key works like a shop calculator: 200 + 10% gives 220. Switch to Scientific for roots, powers and trigonometry in DEG or RAD, and find earlier answers in the History list.
