Hi,(adsbygoogle = window.adsbygoogle || []).push({});

First: Hello, Physics Forums (this is my first post)!

Now to business.

I am trying to enter the Distance Forumula:

m = sqrt([x_{2}-x_{1}] + [x_{2}-x_{1}])

into the Equation Solver on the HP-50g. However, I cannot find a way to subscript variables. Of course, I could just enter,

m= sqrt ([A_{2}-B_{1}] + [C_{2}-D_{1}])

but that makes things a little confusing. Is there a way to subscript variables, and have them act independently?

Thanks,

Pianoman
