I'm helping my grandson with his math class. I solve his current problem set before sitting down with him. I check my work with AI (Gemini) to make sure I don't make any arithmetic mistakes. This week's problems involve a picture of parallel lines intersected by other lines. Each of the angles formed has an algebraic expression. You have to solve for x by setting up an equation based on the relationship of the angles involved. Twice in six problems Gemini got the relationship of the angles wrong. I would have thought my now such an easy problem wouldn't generate an error. Is my expectation out of line?
