## Subscript in HTML using Mathjax

It is possible to render subscript in mathemetical equation using underscore _ in mathjax. You can use multiple levels of subscript.

  Reference Rendering division in HTML /* Referencedesigner.com Mathjax tutorial - Subscript */ A simple equation showing usage of subscript
$$x_1 +x_2+ x_3 = 43$$
You can use curly brackets to render subscript so length more than 1 character.

$$x_{i1}$$

You will also have to use curly bracket to render sub subscript.

$$x_{i_2}$$
Notice that x_i_2 in above will render error.

Subscripts can be combined with superscript as in

$$x_i^2$$

Aubscripts can also be applied before a literal as in

$$_bx^c$$ 

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

### Exercises

1. Render the following using Mathjax ( Use the above example and make changes into it.)

$x_i^2+y_i^2=z_i^2$
