Press the green flag to start Jo can only handle yes or no questions. To get to calculator (little robot icon) press enter without typing anything in the Do you have a question for Jo? box, wait for Jo to answer. Then click on the robot icon. (Answers for Jo are randomly selected, please do not be offended by anything "he" says) You have to start the project again to get back to Jo from Calculator.
