Tbh, so what? I googled "symbolic math engine in Typescript that can perform evaluation and simple expression reductions over +-/*()" and got what looks to be viable answers without using any AI model at all. Reciting well established things from memory isn't terribly interesting. Show it a novel codebase and have it implement something within it.

TBH, while your point is a fair one, your attitude is off-putting and needlessly condescending.

So, a natural question would be why a model would ever get it wrong?
