Calculator History and Memory: Viewing, Saving and Clearing Past Results
Published · 3 min read · By The Samsung Calculator editorial team
Which calculators keep a running history, how to bring it back on Windows, iPhone, Android and Casio models, and how to clear it when you are handing the device to someone else.
The short answer is that a full scientific calculator with trigonometry, logarithms, powers, roots, memory and a running history — keyboard friendly and instant. Everything below explains why, and where that answer stops being true.
Why it works this way
Understanding the mechanism matters more than memorising a result. Once you can see which quantity drives the outcome, you can sanity-check any number a tool hands you — including ours — and spot when an input is wrong before the answer misleads you.
A worked example
Open the Scientific Calculator with its default values, then change a single input and note the effect. A full scientific calculator with trigonometry, logarithms, powers, roots, memory and a running history — keyboard friendly and instant.
Common mistakes
Three mistakes account for most wrong answers here: mixing units without converting, applying a rate for the wrong period (annual where monthly was needed, or the reverse), and rounding partway through instead of at the end. Each one is easy to make and easy to avoid once you are watching for it.
