This seems crazy to me, but I often use google search for simple calculations when I'm using chrome. Today, I did this and I was met with an AI generated answer. Why on earth would I want an AI generated answer, when the calculator worked perfectly? What is going on? Whoever turned this on at google, please, please, turn it off.
