How to Use the Memo Calculator
A standard calculator shows only the current result — once you move on, the steps are gone. The Memo Calculator adds a note to every entry and logs the full history, making it ideal for itemized estimates, splitting group expenses, on-site invoicing, and any task where you need to track what each number represents.
Using it is straightforward: pick an operation (+, −, ×, ÷), enter a number, optionally type a label (like "Groceries" or "Labor"), and click "Add Entry." The running total updates and the entry is added to the history below. You can chain as many operations as you need — add categories one by one, then review the full breakdown at the end.
When finished, click "Copy History" to copy the entire log as plain text. Paste it into a notes app, email, or spreadsheet for your records. The history lives only in browser memory, so it resets when you close or refresh the page — always copy before leaving if you need to keep it.
