It is important that you work the problems. Write your answer in the box provided. If you press any of the buttons (Answer, Store or Compute) and you are working within your workspace, your answer will be stored so that it will be there when you come back to the page.
For questions that do not have a Compute button, you can type anything that you like into the answer box. For questions that do have a Compute button, you will need to type the correct kind of thing (expression, statement, etc.) into the box. You can add comments by writing %% in front of each comment line. For example, if the expression is supposed to be an expression, you might write
%% I have to remember to use * to mean multiplication. 20 * 30Anything following %%, up to the end of the line, is ignored when the Compute button is pressed. (But it is remembered for later.)
