A line-by-line maths working editor · exports LaTeX
TypeMaths is a free online maths editor for writing working step by step. Type sqrt, int, / and ^ and it typesets as you go; press Enter and the line copies down, so you only change what changed; then copy or export the whole page as LaTeX for Overleaf, Word or Google Docs. There is no LaTeX to learn, and no account needed.
Free · Runs in your browser · Saves as you type
⌘+Enter on the substituted line evaluates (27+9)−(1+1) and writes 34 underneath.
TypeMaths does not do your maths for you. It removes everything between having a thought and seeing it written down properly.
int becomes ∫, sqrt becomes √, "/" builds a fraction, "^" a power. Type "matrix" for a matrix, or "augment" for an augmented one.
Every working step starts as a copy of the one above it, so you only edit what actually changed — the rest stays put, and the equals signs stay aligned.
Substitute your numbers, then evaluate the line. The result appears underneath, rounded the way you asked, in degrees or radians.
Copy the whole page to the clipboard as LaTeX and paste it into Overleaf, or download it as a .tex file. Screenshot mode gives you a clean image for Word, Google Docs or a slide.
Every worksheet below is a real TypeMaths page, animated exactly as it would be typed.
Linear algebra
Press Enter and the whole line copies down, augmented matrix included. Edit only the entries that changed, and label each step as you go.
Solve 2x + y = 5 and x + 3y = 10 by row reduction.
[2113∣∣∣∣510]R₁ ↔ R₂
[1231∣∣∣∣105]R₂ → R₂ − 2R₁
[103−5∣∣∣∣10−15]R₂ → −⅕R₂
[1031∣∣∣∣103]R₁ → R₁ − 3R₂
[1001∣∣∣∣13]Every line is one Enter press. The → between steps is picked from the relation dropdown.
Physics
Work the algebra the way you would on paper. When you reach numbers, TypeMaths evaluates them — with your rounding and angle units.
A car accelerates from 10 m/s to 25 m/s over 120 m. Find a.
v2=u2+2asu = 10, v = 25, s = 120
a=2×120252−102⌘+Enter evaluates (25²−10²)/(2×120) = 2.1875, shown to 2 decimal places.
Chemistry
Reaction arrows and equilibrium arrows are relations, the same as = and ≤ — choose one per line and the columns stay aligned.
Balance the combustion of propane.
C3H8+O2→CO2+H2O3 carbons, and 8 hydrogens make 4 waters.
C3H8+O2→3CO2+4H2OThat needs 6 + 4 = 10 oxygens, so 5 O₂.
C3H8+5O2→3CO2+4H2OReversible reactions take ⇌ instead.
N2+3H2⇌2NH3→ and ⇌ come from the same relation dropdown as = and ≤.
Binomial theorem
Type \choose or \binom for n-choose-k and keep working. When a line reaches numbers, TypeMaths evaluates it — binomials included.
Find the coefficient of x² in the expansion of (1+(1+x))⁴.
(1+(1+x))4Each (1+x)ᵏ contributes ᵏC₂ copies of x² — sum over k ≥ 2.
c2=(42)(22)+(43)(32)+(44)(42)The closed form ⁴C₂ · 2⁴⁻² says the same.
c2=(42)⋅22Both ⌘+Enter presses return 24 — the coefficient sum and its closed form agree.
Derivations
Text lines annotate the working, and every line is numbered automatically — number, letter or roman, whichever the question wants.
Derive the quadratic formula by completing the square.
ax2+bx+c=0Divide through by a.
x2+abx+ac=0Complete the square, then move the constants across.
(x+2ab)2=4a2b2−4acTake the square root of both sides.
x+2ab=±2a√b2−4acThe + on a line adds the prose above it. Line numbers cycle: 1 → a → i → hidden.
The same page works for homework, for a worked example, and for the LaTeX you were about to type by hand.
Students
Write each step on its own line, the way you would on paper, and hand in something that looks typeset. Fractions, roots, integrals and matrices come out right without an equation editor, and the equals signs stay lined up.
TypeMaths for studentsTeachers and tutors
Type a worked solution once and it is a properly formatted worksheet: numbered questions, the wording in prose, the working underneath. Export it as .tex, screenshot it into a handout or a slide, or share a link so students can follow the steps.
TypeMaths for teachers and tutorsOverleaf and LaTeX users
Type the working like handwriting — sqrt, int, / and ^ — and copy the page as LaTeX. Paste it into Overleaf or any .tex document, with the alignment already done. Every LaTeX command still works if you want to type it yourself.
TypeMaths for LaTeX and OverleafGrow a matrix to any size, or use an augmented one for simultaneous equations. Adding or deleting a row keeps both sides of the divider in step.
Every line is numbered automatically — 1, a, or i — and a "+" adds a line of ordinary text above it for the question wording or a comment.
Copy a page as LaTeX straight to the clipboard for Overleaf, or download it as .tex. Import an exported file back in — that is how you share a worksheet.
Flip the worksheet to black-on-white typesetting, ready to screenshot into a document, a slide, or an assignment.
Move between boxes, delete a line, undo a page, select a whole fraction in one press. Your hands never have to leave the keys.
Work is kept in your browser the moment you write it, with no account. Sign in and the same worksheets follow you to your other devices.
No. Type sqrt, int, pi or theta and they typeset themselves as you go, and "/" builds a fraction. If you do know LaTeX, every command still works — type a backslash and keep going. Either way you get LaTeX out: copy the page as LaTeX whenever you need it.
It is a maths working editor that exports LaTeX. An equation editor gives you one formula at a time; TypeMaths gives you a page of working — every step on its own line, equals signs aligned, numbered questions and prose in between — and the whole page copies out as LaTeX. Type it the way you would write it, then paste the result into Overleaf or download a .tex file.
You never leave the keyboard or click through a palette: sqrt, int, "/" and "^" typeset as you type, and Enter copies the line down so the next step starts where the last one ended. When you are done, paste it into your document as LaTeX or as a screenshot. It is free, and if what you need is working rather than a single formula, it is a real alternative to MathType and Word's equation editor.
No, and that is deliberate. TypeMaths types your working, not your answers: you write each step, and it keeps the maths typeset and the equals signs aligned. When a line reduces to arithmetic, press Cmd or Ctrl plus Enter and it evaluates that line and writes the result underneath.
Yes. You can open a worksheet and start typing without an account — your work saves in your browser as you type. Make a free account and it syncs across your devices instead.
Yes. A page is a worksheet: numbered questions, a line of ordinary text for the wording, and the working underneath. Type a worked solution once, then export it as .tex, screenshot it into a handout or a slide, or share a link to the page. There is a library of ready-made worksheets to start from.
Yes. Copy the page to your clipboard as LaTeX and paste it into Overleaf or any .tex document, or download it as a .tex file. For Word, Google Docs or a slide, screenshot mode renders the worksheet as clean black-on-white typesetting to paste in as an image.
Yes. Tapping a box opens a maths keyboard with its own Evaluate button, and a tools drawer for inserting matrices, adding text lines, and deleting rows or columns.
Yes. Reaction arrows and equilibrium arrows sit in the same relation menu as = and ≤, so a balanced equation lines up like any other working. Physics rearrangements evaluate with your choice of angle unit and decimal places.
It is free, it needs no account, and the first line is already waiting for you.
