MathML Basic Elements
- The most basic elements of MathML are: mrow, mi, mo and mn.
Basic Elements
| Index | Elements | Descriptions |
|---|---|---|
| 1. | <mrow> element | The MathML <mrow> element is used to group any number of sub expressions horizontally. |
| 2. | <mi> element | The MathML <mi> element is used to specify an identifier. |
| 3. | <mo> element | The MathML <mo> element is used to specify an operator in a broad sense. |
| 4. | <mn> element | The MathML <mn> element is used to specify a numeric literal. |
For Eg: To write x + y = 5, the equivalent MathML Code are:
Sample Code
<mrow>
<mrow>
<mi>x</mi>
<mo>+</mo>
<mi>y</mi>
</mrow>
<mo>=</mo>
<mn>5</mn>
</mrow>Output

<mrow> element
- The MathML <mrow> element is used to group any number of sub expressions horizontally.
<mi> element
- The MathML <mi> element is used to specify an identifier. For ex: The name of a variable, a continuing , a function, etc.
- It automatically renders the identifier using an italic font, if the identifier is one character long; otherwise the name is rendered with help of normal, upright font.
<mo> element
- The MathML <mo> element is used to specify an operator during a broad sense. For Ex: addition operator '+', fence operator '{' or a separator ','
- The appropriate amount of space is added on the left and on the right of an <mo> element based on the textual contents of this element.
- For ex: In the above expression you replace <mo> + <mo> by <mo> , <mo>, this may suppress the space at the left of the mo element.
<mn> element
- The MathML <mn> element is used to specify a numeric literal.
- For eg: PI should be specified as <mi>PI</mi> and not as <mn>PI</mn> while 3.14 should be specified as <mn>3.14</mn> and not as <mi>3.14</mi>.
