ChatGPT tries to do your homework, 1.1

ChatGPT

First of all,

• a little Lewis Carroll
• Is the moon made of green cheese?

• Exercise #2 -- whoops! The importance of parentheses....

  

• Exercise #9

  

• Exercise #11: this looks like a whoops, too. First negation is right, but the second isn't!

  

• Exercise #15c:

  

• Exercise #15d: whoops

  

  (Notice that chatGPT corrected the compound statement spelling, but incorrectly turned it into an if and only if!)

• Exercise #17b:

  

• Exercise #17c:

  

• Exercise #19

  

  Once again, there's confusion about "only if", which chatGPT turns into an "if and only if" (far too strong).

  In addition, chatGPT screws up the "is a necessary condition", writing the converse.

• Exercise #23a: hilarious disconnect between truth table and conclusion!

  

• Exercise #23

  

• Exercise #47

  

• Exercise #57: whoops!

  

• Exercise #57, take 2: still a whoops!
