Can one Bitcoin script add values from another script?

Can a bitcoin script handle a calculation and then take that result to add it to another script's total? Just trying to wrap my head around what Bitcoin can and can't do. I get that bitcoin scripts aren't turing complete, but I think they can pull off a "babylonian square root" in a limited way if you just repeat the loop code. Plus, with ethereum's gas fees, the precision of these functions gets hit anyway. I'm looking to implement my governance protocol on bitcoin. It’s based on a project that originally was a pyramid scheme called proof of weak hands. That smart contract uses the babylonian square root function. I asked chatGPT, and it mentioned that scripts can be linked, but I wanted to double-check here to make sure that’s not just a mix-up.
