Why Use ZeeSharp's Advanced Calculator?
Unlike a basic four-function calculator, this tool correctly handles order of operations (PEMDAS/BODMAS), parentheses, and percentages — so expressions like (12+8)×3−5% evaluate exactly the way they would on paper. It also keeps a full session history and supports memory storage, so you can build up multi-step calculations without losing track of intermediate results.
Features
- Correct order of operations — multiplication/division before addition/subtraction, exponents first, parentheses always respected
- Memory functions — M+, M−, MR, MC for storing and recalling values across calculations
- Calculation history — every result is logged; click any past entry to reload it
- Keyboard support — type expressions directly, press Enter for =, Backspace to edit
- Square, square root, reciprocal and percentage in one click
