Donghoan Lee Assignment Orientation Assignment due 09 24 2021 at 11 59pm EDT FA21 BL MATH M118 11252 1 1 point Understanding WeBWorK Problem Pages The WeBWorK screen is divided into several areas each used for a different purpose You will need to understand these in or der to use WeBWorK effectively At the upper left are the navigation buttons that allow you to move from problem to problem The Next and Previous buttons naturally send you to the next and previous problems The Problem List button takes you back to the opening page for the homework set the one that lists all the problems and gives the instructions for the homework set The area below the navigation buttons is where WeBWorK tells you about your score for the current problem When you have submitted your answers this is where you will be given information about what answers you got right and wrong This area also shows you how many points a problem is worth The main part of the page is the text of the problem you are trying to answer including blank boxes for you to enter your an swers There aren t any such boxes on this page because you are not being asked any questions here but usually there will be one or more answer blanks on a page Below the problem text is a message area where you may be informed about how partial credit is handled in multi part problems Other information also may appear there such as a message indicating that the due date is passed or that answers are available In the panel at the left instead of the list of homework sets you now have a list of the problems within this assignment You can go to any problem just by clicking on it There is also a progress bar which gives you a visual indication of your progress on the set and following each problem number an icon indicating if the problem has been answered corrrectly or still needs to be worked on to get full credit The buttons at the bottom of the screen including the Sub mit Answers button are discussed in the next problem At this point you can get credit for Problem 1 by pressing the Submit Answers button at the bottom of the page even though there was no answer to submit and then pressing the Next button at the top of the screen to go on to the next problem 2 1 point Controlling WeBWorK The buttons at the bottom of the screen are what cause WeB WorK to process your answers Nothing that you type will have any effect until you press one of these buttons The Submit Answers button causes WeBWorK to check your answers and report your score for the problem Usually you can continue to work on a problem until you get it right so don t be afraid to submit your answer even if you have only 1 nished parts of the problem or are not sure of the correct ness of your answer Sometimes e g for multiple choice or true false type questions your instructor may limit the number of attempts allowed on a problem At the bottom of the page you will see how many attempts you have remaining If the due date is passed and the answers are available you can click the Show Correct Answers button before pressing Submit If you do the correct answer s will be displayed in the answer area at the top of the screen along with the answers you have provided If you have typed in a complicated answer or are being told your answer is incorrect when you think it s right you may want to use the Preview My Answers button This will ask WeB WorK to display at the top of the page its interpretation of what you have entered This can be used to help spot errors in your typing and verify that WeBWorK understands your answer the way you intend it to And it does not count as an attempt on the problem This is discussed further in a later problem The User Settings link under the MAIN MENU at the left has a Change Display Options section that allows you to change how the problem is displayed The equations within the problem can be represented in two different ways images mode produces accurate mathematical nota tion with the disadvantages of being slightly slower and not printing well if you want to print out a single problem MathJax mode is the default choice what WeBWorK uses unless you tell it otherwise It uses Cascading Style Sheets CSS with web fonts or SVG instead of bitmap images or Flash so equations scale with sur rounding text at all zoom levels MathJax is compatible with screenreaders and provides zoom for everyone Choose whichever mode is most comfortable for you You can always select a different mode if a particular problem needs it Here is a sample of some simple mathematics x2 3 and a more complicated expression x 1 x 2x 1 Try changing the display mode by clicking the User Settings link selecting the im ages radio button pressing the Change User Settings button and then displaying problem 2 again Then change the display mode to back to MathJax mode for the rest of the homework set The Show saved answers checkboxes tell whether you want WeBWorK to ll in the answer blanks with your previ ous answers or not If you like you can test this out on the next problem since there are no answer blanks in this one You are now ready to learn how to enter answers into WeB WorK Press the Submit Answers button to get credit for this problem and then press the Next button at the top of the page to go on to the next one 3 1 point Typing in Your Answers Here are the standard symbols that WeBWorK along with most other computer software uses for arithmetic operations Symbol Meaning Addition Subtraction Multiplication Division Example 3 4 7 3 4 1 3 4 12 3 4 75 or Exponentiation 3 4 81 or 3 4 81 Sometimes WeBWorK will insist that you calculate the value of an expression as a single number before you enter it For ex ample calculate the value of 4 1 5 4 5 and enter it in the following blank Here you have to enter a single in teger the question is testing whether you can do the operations correctly 4 1 5 4 5 Most often you will not have to simplify your answer but can let WeBWorK do this for you The following blanks are all ex pecting the value 16 Try entering it several different ways such as 7 9 18 2 8 2 32 2 and 4 2 Note pressing the Tab key on your keyboard will move you from one answer box to the next 16 or or or or WeBWorK also understands that quantities written next to each other are supposed to be multiplied For example you can enter 9 7 instead of 63 …
