This walkthrough takes a MathPad draft from an empty formula to a verified copy in another tool. You will build f = (x₁ + y²) / (z + 1) as a structured expression, inspect its parts, exercise the formula clipboard and history, then copy the representation that best fits your next destination.
Decide Where the Formula Will Live
MathPad keeps the editable formula, selection, and history only for the current app session. An entry in the formula explorer is not a saved formula body. Switching to another local draft and returning during the same session may restore your work, but a refresh, another device, or a later session will not.
Before starting, choose an external destination that can save the representation you need. This might be a LaTeX or Typst document, a data file, a web project, or a plain-text note. Keep that destination ready so you can paste and save the export before leaving MathPad.
•Stay in one session - Do not refresh the app while following this guide. Avoid closing the browser tab until the external copy is saved and checked.
•Choose a compatible destination - Decide whether the next tool expects LaTeX, Typst, MathJSON, MathML, or Plain text. If you are unsure, keep a readable Plain text companion as well as the richer format.
•Work independently - MathPad does not provide shared editing, presence, or collaborative history. Finish the export yourself before handing the result to another person.
For a fuller explanation of the editing model and its current boundaries, see the MathPad overview.
Start With an Empty Formula
•Open MathPad - Open MathPad from Apps and browse to the space area or folder where you want to begin.
•Create the draft - Choose New formula. The editor opens with a blank formula rather than a sample expression or prefilled undo history.
•Focus the formula - Click or tap the empty formula field. The caret or placeholder highlight should appear in the rendered editing area.
•Confirm the session boundary - If this formula matters beyond the next few minutes, keep your external destination open now. The local draft can be convenient during this session, but it is not a durable backup.
If you accidentally open an existing explorer entry, it may still show an empty editor shell because previously saved formula content is not loaded. Return to the explorer and choose New formula when you want a known-empty starting point.
Build the Structured Expression
Start with ordinary typing, then insert the parts whose shape matters. The exact expression is only an example; the important skill is moving into and out of structural placeholders without flattening the formula into source text.
•Type the opening text - Enter f = with the hardware keyboard or the Latin and operator layers of the formula keyboard. The characters should appear directly in the rendered formula.
•Insert a fraction - Open Structure and choose the enabled Fraction command from the ribbon. You can instead open / commands, search for /fraction, and commit the enabled result, or choose the fraction key from the formula keyboard's Structures layer.
•Check the first placeholder - The caret should move into the numerator. If a Fraction command is visible but disabled, read its unavailable reason and choose another enabled fraction entry point; a disabled command leaves the formula unchanged.
•Enter a subscripted symbol - Type x, then choose the enabled Subscript command, search /index, or use the corresponding formula-keyboard key. Type 1 in the subscript placeholder.
•Return to the numerator - Press Tab to move forward from the subscript. If the highlight moves past the intended position, use Shift+Tab to move back. Type + y after x₁.
•Add the power - Choose the enabled Superscript command, search /power, or use the power key. Type 2 in the exponent placeholder, then press Tab to leave it.
•Move to the denominator - Continue with Tab until the denominator placeholder is highlighted. Use Shift+Tab if you pass it. Type z + 1.
•Leave the fraction cleanly - Press Tab until the caret is after the completed fraction. The visible result should read like f = (x₁ + y²) / (z + 1), with a stacked fraction rather than typed slash characters.
The ribbon, / commands, command browser, and formula keyboard all use the same supported insertion actions. You can mix them freely. The catalog is broader than current editing support, however, so availability matters more than visibility. Never assume that a displayed advanced command will work; MathPad explains disabled items instead of applying a partial change.
Check the Formula From More Than One View
The rendered formula shows its appearance. Structure and Symbols help you verify that the expression also contains the parts you intended.
•Open Structure - Review the read-only outline. Look for the formula row, fraction, numerator and denominator slots, subscript, superscript, symbols, numbers, and operators.
•Find unfinished slots - Check for an empty placeholder or an issue marker. If one appears, activate its Structure row to select the matching part in the formula, then type the missing content.
•Select the fraction - Activate the Fraction row in Structure. The fraction should become the selected part in the rendered formula rather than selecting unrelated text around it.
•Open Inspector - Review the selected part's type and current presentation values. Display mode, alignment, size, notation preference, and source preservation are inspection values in the current editor; they are not editable settings.
•Open Symbols - Review the extracted variables and operators. The list should account for f, x, y, and z, along with the formula's operations. Repeated occurrences may appear separately.
•Trace a symbol - Activate a supported x or y row. MathPad should select the originating part in the rendered expression, which is useful when the same name appears more than once.
At this checkpoint, fix any missing placeholder or unexpected symbol before continuing. Exports are generated from the current formula, so an unnoticed structural mistake will be carried into every format.
Exercise the Formula Clipboard and History
MathPad's formula clipboard preserves supported selected structures inside the current session. It is different from copying an export to the operating-system clipboard.
•Select the numerator - Use Structure to activate the numerator row, or select the complete numerator in the rendered formula.
•Copy the selection - Use Copy from the formula menu or the standard copy shortcut while the formula has focus. Copying stores compatible MathPad formula content; it does not change the expression.
•Choose a paste target - Place the caret after the fraction, where a copied formula part can be inserted without replacing the original numerator.
•Paste once - Use Paste from the formula menu, the standard paste shortcut, or the formula keyboard control. Confirm that the pasted numerator keeps its subscript and superscript instead of becoming unrelated characters.
•Undo the test paste - Open History and choose Undo, or use the standard formula undo shortcut. The extra numerator should disappear and the original formula should remain intact.
•Redo once - Choose Redo. The structured duplicate should return with the selection restored to a useful position.
•Restore the intended result - Choose Undo again so the formula ends as f = (x₁ + y²) / (z + 1). In History, the paste should now be available on the redo side.
Do not choose Clear while learning this flow unless you intentionally want to discard the session's undo and redo stacks. Clear does not erase the visible formula, but it removes the local recovery trail. History also ends with the app session and cannot recover a draft after refresh.
Pasting a formula copied from an arbitrary operating-system application is not a general MathPad import path. If Paste is unavailable, first confirm that a supported MathPad selection was copied in this session and that the current caret is a compatible insertion target.
Choose the Export for the Next Job
Open Export and select the representation according to what the receiving tool understands, not only by which preview looks familiar.
•Choose LaTeX for TeX-oriented writing - Copy LaTeX when the destination accepts formula-level LaTeX. Source replacement inside MathPad accepts only a bounded supported subset, so do not assume every external macro can be brought back as editable content.
•Choose Typst for a Typst document - Copy Typst when the formula will be placed in a Typst authoring workflow. This is formula content, not a complete document.
•Choose MathJSON for structured exchange - Copy MathJSON when the receiving tool explicitly supports its structured mathematical representation. Keep the complete copied value rather than extracting only the visually familiar names.
•Choose MathML for web or accessibility work - Copy MathML for a destination that accepts mathematical markup or needs a web-oriented accessible representation.
•Choose Plain text for a readable fallback - Copy Plain text for notes, search, messages, or systems that do not understand richer formula formats. It is easy to inspect, but it may not preserve every authoring distinction.
If the destination supports more than one format, prefer the richest representation it reliably parses and keep Plain text as a quick comparison aid. A visually similar string is not always an exact round trip.
Review Diagnostics Before Copying
The Export panel shows source-preservation information and a conversion report for the current formula. Treat these as part of the export decision.
•Check source information - Review the source format, source value, and preservation status shown for the formula. Source preservation describes the current representation; it does not make the MathPad draft durable.
•Read every Warning - A warning means the output may use a fallback or may need attention in the target tool. Decide whether the destination can accept that result.
•Treat Loss as consequential - A loss means some notation or authoring intent could not be carried across exactly. Try a different export format, simplify the affected part, or keep an additional representation that preserves the missing information.
•Refresh if needed - If the formula changed while Export was open, use Refresh for the chosen row when it is available, then review the report again.
•Use Copy, not Open - Export preview through Open is currently unavailable. Choose Copy on the format row to place the generated value on the operating-system clipboard.
For the representative fraction, inspect the copied string closely enough to recognize both grouped parts, the subscript on x, and the power on y. Do not proceed merely because the Export panel says a format is ready.
Paste, Save, and Verify Outside MathPad
Copying is not the finish line. The formula is preserved only after the receiving tool has accepted and saved the representation.
•Paste into the chosen destination - Switch to the prepared external document or file and paste the export value without editing away grouping characters, markup, or quotation marks required by that format.
•Save the destination - Use the destination's normal save or publish action. If it has no durable save behavior, choose a different destination before leaving MathPad.
•Verify the stored value - Reopen or re-read the saved destination. Confirm that the pasted value is still present after saving rather than relying on an unsaved editor buffer.
•Check the mathematical result - When the destination can render or parse the format, verify the numerator x₁ + y², denominator z + 1, and leading f =. For Plain text, compare the grouping and script meaning directly. For MathJSON or MathML, make sure the receiving tool accepts the complete value without an error.
•Keep a companion when useful - If the primary format is difficult to inspect, also copy and save Plain text or MathML as a readable or accessible companion, then label the two versions clearly.
•Leave only after verification - Once the external copy is saved, reopened, and compared with the rendered MathPad expression, it is safe to close or refresh the session. Until then, keep MathPad open.
Solve Common Problems
•A structural slot is still empty - Open Structure, activate the placeholder row, and fill it. Use Tab and Shift+Tab to move between nearby slots without rebuilding the expression.
•A command is visible but cannot be chosen - Read its disabled reason. Many catalog entries are present for discovery before their insertion is supported, and choosing one does not change the formula.
•A source replacement is refused - MathPad accepts a bounded supported LaTeX-style source subset and rejects empty, oversized, malformed, or disallowed input. Build the expression with enabled visual or keyboard commands, or simplify the source before trying again.
•Paste does nothing - The formula clipboard needs a supported MathPad selection and a compatible target. Operating-system formula paste is not a general importer, even though Copy in Export can place an output string on that clipboard.
•Undo does not reach an earlier session - History is local to the current app session. It cannot restore content after refresh, from another device, or from a later visit.
•The export looks different in the destination - Return to Export and review Warning and Loss entries. Try the destination's native format, keep a second representation, or simplify notation whose conversion is approximate.
•Appearance controls cannot be changed - Inspector and Help & settings currently show presentation and preference values for review only. They do not apply changes to the formula.
•The draft disappeared - A refresh or ended session removes the editable formula content. Recover the verified external copy; the explorer entry alone cannot restore it.
AI formula actions, handwriting input, and realtime collaboration are not available in this workflow. Use the enabled editing tools and the explicit export check instead of waiting for those surfaces to modify or preserve the formula.
Continue With MathPad
You now have a structured formula in MathPad and a durable, checked representation outside the session. If the formula belongs in Visual Space content, continue with Add a MathPad Formula to an Article and verify the stored article snapshot separately.
