Line-by-line working, typed
TypeMaths is a free online editor for writing out mathematical working step by step. Type sqrt, int, / and ^ and they typeset as you go; press Enter and the line copies down, so the next step starts where the last one ended and the equals signs stay lined up. It looks like the page you would have written by hand — and it does the arithmetic when you ask.

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.
TypeMaths does not do your maths for you. It removes everything between having a thought and seeing it written down properly.
sqrt, int, pi, theta; "/" for a fraction, "^" for a power. It typesets as you go, so the line looks like maths while you are still typing it.
Press Enter and the whole line copies down. Change the part that changed, and the equals signs stay aligned down the page, the way they would on ruled paper.
When a step comes down to numbers, evaluate it and the result appears on the next line. The working stays yours; the calculator is there when you ask.
Screenshot mode gives clean black-on-white working for a document or a slide; Copy LaTeX or Export .tex give the same page as LaTeX; a share link gives it as a web page.
Two more pages of working, animated exactly as they would be typed.
Calculus
Type the integral, write the antiderivative, substitute the limits — then let TypeMaths do the arithmetic.
⌘+Enter on the substituted line evaluates (27+9)−(1+1) and writes 34 underneath.
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.
A "+" on any line adds a line of ordinary text above it — the question, or a note on why the step is allowed — and the lines number themselves: 1, a, i.
Move between boxes, delete a line, undo a page, select a whole fraction in one press. Nothing on this page needs the mouse.
Flip the page to black-on-white typesetting, ready to paste into Word, Google Docs, a slide or a marking scheme.
Close the tab and come back — the page is still there, with no account. Sign in only if you want the same pages on your other devices.
Yes. TypeMaths is built around working rather than single equations: every step is its own line, pressing Enter copies the line down so you edit only what changed, and the equals signs stay aligned down the page. Fractions, roots, integrals and matrices typeset as you type them.
You never leave the keyboard or click through a palette, and you never fight the alignment. Type sqrt, int, "/" and "^" and they typeset; press Enter for the next step. The working reads the way it would on paper, and it can be pasted into a document afterwards as LaTeX or as a screenshot.
No, and that is deliberate. You write each step; TypeMaths keeps it typeset and aligned. When a line reduces to arithmetic, press Cmd or Ctrl plus Enter and it evaluates that line and writes the result underneath — a check, not a shortcut.
Yes. A "+" on any line adds a line of ordinary text above it for the question wording or a comment, and every line is numbered automatically — 1, a, i — so a reader can follow the steps.
Screenshot mode renders the page as clean black-on-white typesetting to paste into Word, Google Docs or a slide. Copy LaTeX puts the page on your clipboard for Overleaf, Export .tex downloads it, and a share link lets someone read the page in their browser.
Yes. Tapping a box opens a maths keyboard with its own Evaluate button, and a tools drawer for matrices, text lines, and deleting rows or columns.
Free, no account, and the second line is one Enter away.
