**Writing Exponential Expression**

Writing exponential expression in HTML is quite easy. We only have to use superscript tag to raise the exponent, just like shown in the examples above. If you want to write your own HTML exponential expression, all you have to do is copy the HTML codes from the image above and change the strings written in red and blue.

**Writing Polynomial Expression**

Polynomial Expressions are simply sequences of exponential expressions. Therefore, the HTML code for polynomial expressions are simply sequences of HTML code for exponential expression. You will only have to add the plus(+) and minus(-) signs between exponential terms. If you want to write your own HTML Polynomial expression, just copy the HTML codes from the image above and change the strings written in colors.

**Writing Fractional Expression**

Fractional Expressions are a little bit harder to write in HTML. We have to use the table tag to put each of element of the fraction into place. Using the table tag is actually quite easy. You only have to remember that a

tag have to be ended by a

tag. Between

and

pair, you will have to place several and pairs to divide the tables into several rows. Accordingly between a and pair, you can place several and pairs to divide the rows into several columns.

As complicated as it may seems, you have the images above as your guide. For a start, you only have to copy the HTML codes shown above and change the strings or characters written in color.

**Writing Rational Expression**

In its very basic form rational expressions are polynomial expression inside a fractional expression. To write rational expression using HTML, you will have to replace strings written in red and blue in fractional expression with the HTML code for polynomial expression of your choice.
