Frequently asked questions
Does it follow order of operations?
This is a basic four-function calculator — operations are applied in the order entered. For expressions like 2 + 3 × 4, use parentheses or compute step by step. For full PEMDAS, a scientific calculator is the right tool.
Can I use the keyboard?
Yes — number keys, +, −, ×, ÷ (or *, /), Enter for equals, and Escape or 'c' for clear all work. Useful for quick calculations without leaving the keyboard.
