A simple equation showing usage of subscript

<br />
$$x_1 +x_2+ x_3 = 43 $$
<br />

You can use curly brackets to render subscript so length  more than 1 character. 
<br /><br />
$$x_{i1}$$
<br /><br />
You will also have to use curly bracket to render sub subscript. 
<br /><br />
$$x_{i_2}$$
<br />

Notice that x_i_2 in above will render error.

<br /><br />
Subscripts can be combined with superscript as in 
<br /><br />
$$x_i^2$$
<br /><br />
Aubscripts can also be applied before a literal as in 
<br /><br />
$$_bx^c$$

Try this example here. and see subscript using _ works.
