[Blindmath] accessible talking calculators

[kroskos at cox.net]

Hello, 

I am trying to navigate the first of two required math classes in an online setting. I find that my simple talking calculator is not sufficient for certain functions such as square roots, exponents and logs. Is there such a thing as a talking calculator with advanced features, and if so, where can I find one, and how much might it cost. I am realizing that in the class I need to take next, there may be many advanced calculations required. 

Thanks for any input.
