Use a simple calculator online, with every amount kept visible.
Use CalcStory as a basic calculator for addition and subtraction, multiplication and division. It keeps an itemized calculation history, so you can check a shopping total or daily expenses and fix one amount without starting over.
Calculator with history: each amount you enter stays visible, so you never have to remember how you got a total.
Fix one number: tap any item to edit it, or swipe the live answer to move the cursor to the exact digit. The result updates as you type.
Edit saved results: bring a saved calculation back, change one amount, and save the corrected total.
Notes on every calculation: remember what a total was for, like "Groceries, week 3" or "Kitchen tiles".
Search your history: find an old total by note, by result, or by part of the expression.
Operations run from left to right. Use parentheses to control the order: 2 + 3 × 4 = 20, while 2 + (3 × 4) = 14.
The browser calculator needs an internet connection to load. For offline use, download the CalcStory app for iOS or Android.
