Equation writer
Type as you would on paper, or use the keys. Choose the notation your class uses: the page never guesses it.
Settings
Write it
Write x as x or س, a power with ^ (x^2), a fraction with / (1/2), a root with √ or sqrt. The picture follows each character you type.
Use it in class
On the board the expression stays editable: select it to change it or its notation. The picture is a PNG on white.
How to use it
- Choose the notation: Latin (left to right, x, sin, 0–9) or Arabic symbols (right to left, س, جا, ٠–٩). The choice is kept on this device.
- Type the expression, or press the keys; the letters and digits of either notation are read the same way.
- If something cannot be read, the message under the field says what and where.
- For class: put it on the board, where it stays editable, or download it as a picture for a document or a slide.
Worked examples
The same equation in both notations
Typed as 2x + 3 = 7, it reads from left to right in Latin notation, and as ٢س + ٣ = ٧ from right to left in Arabic symbols, the ٢ coming first, on the right.
Powers and roots
x^2 is written x² with the exponent at the upper right; in Arabic symbols it is س² with the exponent at the upper left, since the expression is read from the right. The root sign opens to the right in Latin notation and is mirrored in Arabic symbols.
Quick reference
| Meaning | Typed as | Latin notation | Arabic symbols |
|---|---|---|---|
| the variable x | x س | x | س |
| the variable y | y ص | y | ص |
| a power | ^ ² | x² | س² |
| a square root | sqrt √ | √x | √س |
| a fraction (written stacked) | / | 1/2 | ١/٢ |
| sine | sin جا | sin x | جا س |
| cosine | cos جتا | cos x | جتا س |
| tangent | tan ظا | tan x | ظا س |
| less than or equal to | <= ≤ | x ≤ 5 | س ≤ ٥ |
| a decimal | . , ٫ | 0.5 | ٠٫٥ |
In Arabic symbols a decimal is written with ٫. ln, log and e keep their Latin forms in both notations: no Arabic form for them was found in a current school book.
Sources
The notation follows the W3C note on Arabic mathematical notation and was checked against current school books from Saudi Arabia, Egypt, Algeria and Morocco (cited as evidence only). Some books use Arabic symbols and others Latin notation, even in one country, which is why the page asks rather than guesses.
