"Math definitions are tricky things.
They are like wishes you make to a genie.
Be very careful with your choice of words.
Otherwise, you end up in trouble."
AI's Math Mistakes
Here, AI does the calculations correctly. But, then makes a mistake in reporting the correct result of 20 working days. Instead, its response starts with the incorrect report of 22 working days.
Here, AI leaps to the false conclusion that a result I found on the generic invertibility of weighted sums of 2x2 matrices can be generalized to nxn matrices. My counterexample convinces otherwise.
