Will GPT ever be able to do MATH?

I have tried in the regular GPT-4, the API trying to develop python code to do this, and now in the amazing GPT Developer. I use one matrix at a time, as small as 4x20. There are detailed rules and constraints uploaded as a document as well. It absolutely fails every time it tries to generate a random selection of findings and add the corresponding cell values. IF I could get this to work, I will be able to replicate 25. Years of R&D and my life will finally have value other than null. Any thoughts???

yes I have used GPT 4 for solving things like partial differential equations. It will be much useful if you paste the rules in the message box.
Not sure how complicated is your work which is worth 25 years of R&D.
