Question 1

How do I use the memory functions (M+, M-, MR, MC)?

Accepted Answer

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.

Question 2

Does this calculator follow order of operations?

Accepted Answer

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.

Question 3

How does the tape history work?

Accepted Answer

The tape history records every calculation you make, similar to a physical receipt. You can scroll through your history, review past steps, and even click on previous items to reuse them. Your history is saved automatically.

Question 4

Can I use keyboard shortcuts?

Accepted Answer

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.

Question 5

Is this calculator free to use?

Accepted Answer

Yes, this online calculator is completely free. It works on any device with a web browser. Your calculation history and settings are synced to the cloud if you sign in, allowing you to switch devices seamlessly.
