Original post body:
I was trying to do a budget breakdown with AI and somehow Claude discounted $1100 (almost 20%) and gave me a minor panic attack ! Essentially it gave me back an expense number which was higher than my income Lol !
Why is Claude and AI bad at basic math and arithmetic in general ? It always seems to f"*k up basic calculations and I don't know if I can trust it with any of my complex data analysis.
