The Calculator app on iPhone keeps a history of all the calculations you’ve made, which can be useful if you need to check your work or find a previous calculation. To see your calculator history, open the Calculator app and then tap on the “History” button in the upper-right corner. This will open a list of all your recent calculations, which you can scroll through to find the one you’re looking for.
The Calculator history can be a helpful tool for checking your work, finding previous calculations, or simply keeping track of your calculations. It’s also a good way to learn from your mistakes and improve your math skills.
