Standard Calculator

How to Use This Calculator

This standard calculator works just like a physical handheld calculator, but with a built-in history tape.

• Keyboard Support: You can type numbers and operators directly from your keyboard. Press Enter for equals and Esc for clear.
• History Tape: Every calculation you make is saved on the right side. You can scroll back to see previous results.

Order of Operations (BODMAS)

This calculator follows the standard mathematical order of operations:

1. Brackets (Parentheses)
2. Orders (Powers/Roots)
3. D/M Division and Multiplication (Left to Right)
4. A/S Addition and Subtraction (Left to Right)

For example, 2 + 3 × 4 will equal 14, not 20.
