How your calculation history works
Automatic saving
Every time you run a calculation on mathsolvers.io, it's saved here automatically — no account, no sign-up, nothing to configure. Just use any calculator and it appears in your history instantly.
Review any calculation
Click Review → on any entry to reopen the calculator with your exact numbers pre-filled. The full step-by-step working appears instantly — great for checking a method, spotting a mistake, or walking through the working again.
Save as PDF
Once you're reviewing a calculation, press Ctrl+P (or Cmd+P on Mac) and choose Save as PDF from your browser's print dialog. A clean copy of the full working saves to your device — useful for revision notes, homework portfolios or sharing with a teacher.
Private & local
Your history is stored entirely in your browser's local storage — it never leaves your device and is never sent to any server. Up to 500 calculations are kept automatically; older ones are removed as new ones are added. Clearing your browser data will also clear your history.
Managing your history
Click the ✕ on any entry to remove it individually — useful for tidying up duplicates or calculations you no longer need. To wipe everything at once, use the Clear all history button at the top of the page.
