Free online calculator with a scrollable tape that saves every operation
Search, pin, and annotate entries Includes M+, M-, MR, MC memory keys and export.
M+ adds the current number to memory, M- subtracts it. MR (Memory Recall) displays the stored number, and MC (Memory Clear) resets memory to zero. Use these to store intermediate results during complex calculations.
Yes, our basic calculator follows standard mathematical order of operations (PEMDAS/BODMAS). Multiplication and division are performed before addition and subtraction. Use parentheses if you need to change this order.
The tape history records each calculation like a receipt. You can search/filter long sessions, pin important entries, and switch between list and tape views. Print mode also supports local-only tags and notes for annotated hard copies.
List view shows each calculation as a separate, searchable entry (newest first) — best for reviewing or reusing past results. Tape view lays your calculations out like a printed receipt (oldest first) with a running overall total, so it works like an adding machine when you are totalling a series of numbers such as expenses, a bill, or an invoice. Switch between them with the View toggle above the history.
Yes. Use standard keyboard keys: Enter for '=', Esc for 'Clear', Backspace for 'Delete', and number keys for input. Copy (Ctrl/Cmd+C) and Paste (Ctrl/Cmd+V) also work for transferring numbers.
