I used to have a similar one named yeapook ads1014d. It's definitely not the best in the market. And I don't think it has math function so you would have to do calculations on your own. On the positive side, you can use any 5 volts powerbank to turn it on. To be fair, it gets the job done and the price is fairly acceptable. On top of that, it has a useful signal generator with many different waves.

Regarding the math function, I know that Fnirsi has a website for their products support including software updates, so you might want to double check if they added more features in the latest version.
