MathML provides different tag to represent mathematic and scientific expression but HTML doesn’t provide tag.
5. What is the way to represent a mathematical notation?
There is two ways to represent a mathematical notation:
- Presentational way: It uses markup tags like- mrow, mi, mo etc
- Semantic Way: It uses mark up tags like apply, eq, power etc.
6. What are the MathML elements?

- <maction>
- <math>
- <menclose>
- <merror>
- <mfenced> etc.
7. Which tag is used to draw matrices?

Syntax:
<mtable> <mtr> <mtd></mtd></mtr></mfrac>
8. How can we create an expression a+b=5 in MathML?
In MathML, we can create an expression a+b=5 by using following steps:
<math xmlns=”http://www.w3.org/1998/Math/MathML”>
<mrow>
<mrow>
<mi>a</mi>
<mo>+</mo>
<mi>b</mi>
</mrow>
<mo>=</mo>
<mn>5</mn>
</mrow>
</math>
9. What is the use of <mscarries> tag?
<miscarries> tag is used to create carries, borrows and crossouts.
Syntax:
<mscarries> expression <mscarry> <none/> </mscarry> </mscarries>
10. How can we write an underscript program?
We can write an underscript program by using following command:
<math xmlns=”http://www.w3.org/1998/Math/MathML”>
<mrow>
<munderover>
<mo> ?</mo>
<mn> 0 </mn>
