Boolean Algebra questions and answers will assist students in quickly understanding the basics of the concept. These questions can be used by students to acquire a quick overview of the topics and to try answering them in order to improve their knowledge. Learn the complete solutions for each question to check your answers. To understand more about Boolean Algebra, click here.

The algebra of logic is a Boolean algebra. It works with variables with two different values, such as 0 (False) and 1 (True), as well as logically significant operations. George Boole invented the first way of manipulating symbolic logic, which later became known as Boolean Algebra. Because of its vast applications in switching theory, developing basic electronic circuits, and designing digital computers, Boolean algebra has become a vital tool in computer science.

You are responsible for anything said in class, includingclass announcements. If you have to miss lecture for anyreason, please ask one of your classmates to fill youin on what you missed. The Lecturer and TAs are not responsiblefor keeping you up-to-date if you miss a class.

Discussion section meets two hours per week. (One during summer.)This is an important time to get questions answered about homeworkproblems. No new content will be given in discussion and we do not take attendance, but you are highly encouraged toattend as it will give valuable practice on problems.

We will use an online question and answer service called Piazza.You will all have an account.The link to the to the course page on Piazza is: you have a question about course content, you can go to see if ithas already been asked by another students.If not, you can post the question yourself.The course staff will be checking Piazza several times a dayto update answers to questions posted there.There is also a way for students to collectively edit a responseto a question and for instructors to indicate whether the answeris a good/correct answer.

Before posting a question on Piazza, you should look through the coursematerials or previous Piazza poststo see if you can find the answer to your question.If your question is about the technical content of the course,check the text. If you have an administrative question, check thecourse web page (either the home page with the schedule or this course information page).

Piazza provides a way for you topost anonymously. However, your posts will only be anonymous to other students.The instructors will be able to see the name and uciNetID of any individualwho posts to Piazza.

We will be using the interactive system called iClicker both for class attendance, and for class participation, which will count as 10% of your grade. --> Obtaining assistanceTbe best way to get your questions answered is by comingto lecture, office hours or discussion and asking them there.In particular, office hours and discussion are the best place to ask questions thatrequire a longer answer or some diaglog to get resolved.

The table below shows where to go to for different kindsof questions. Please try to follow the directions there. I really do want to be available for significant problems or issues that may arise. I also really enjoy meeting students in my office hours. However, with a class this size, the amount of email generated from smaller, routine questions can be overwhelming, so I would like you to try and find that answer through other sources first.

Violators of academic honesty policies are subject to the penalties described in the Bren School of ICS policy. They are also subject to an immediate course grade of F, and you will not be allowed to drop the course to avoid the grade. Also be aware that a single documented case of academic dishonesty may preclude you from switching into computing majors, registering for computing minors, joining the ICS Honors Program, and graduating from a computing major with honors.

You can design logical branching with LimeSurvey, which means that you can decide that some questions will be displayed only if some conditions are met like "Show question X if the answer to question Y was Z".

This approach is different from the Jump Branching Logic that is sometimes implemented by other software. In the Jump Branching Logic, the resulting action of a met condition would be to jump to another question (that is to say hide all questions in between). LimeSurvey doesn't implement this Jump Branching Logic method. Instead, if you wish to jump a series of questions, you should simply set the same condition on all the questions you do not wish to be displayed. For example, if the jump condition you want to set on Question2 is "Jump to Question5 if the answer to Question1 is 'Yes'", you can simply:

LimeSurvey makes setting the same condition on multiple questions (and thus implementing Jump Branching Logic) easy by allowing you to "copy" a condition from one question to a series of others. In the above example, you would begin by setting the condition on Question2, then from the same screen, you would copy that condition to Question3 and Question4.

However, it is important to understand that LimeSurvey automatically determines which logical operator to apply. This means that the use of the OR or AND operators is determined according to the context of the condition. In the above example, there is only one scenario. This means that LimeSurvey makes use of Boolean algebra, which means that operator or is "computed" first.

If you select a question-entry (from the Previous questions tab) and if this question uses predefined answers, then the corresponding predefined answers are displayed under the Predefined tab of the comparison value selection.

When you have several conditions, they are ORed together if they share the same tested value. This is the case if the condition applies to several answers belonging to one single question. For example, a condition was applied below to three answers belonging to the same question - if answer to Question 'FavColour' equals 'green' OR answer to Question 'FavColour' equals 'red' OR answer to Question 'FavColour' equals 'blue', then Question 'BirthDate' will be displayed to the survey respondent:

When you have several conditions, they are ANDed together if they don't share the same tested values. For example, you may see below the case for several conditions based on different previous questions - "If answer to Question 'Alcohol' equals 'Y' answer AND answer to Question 'Gender' equals 'F'", then Question 'Alcoholconsumption' will be displayed to the survey respondent:

Now, let's focus on an example to better understand the difference between the two flavours. Let's imagine that we wish to display the 'Pointchoice' Question only if the respondent checks at least one of the tested answers listed under the 'MultipleOrganizations' Question.

As mentioned above, the group of checkboxes flavor allows you to set conditions on all possible answers of the respective question. Therefore, only the options that refer to responsibilities are selected as comparison values below:

Now, let's focus on a similar example. However, we are looking this time only for the most active members to ask them further questions. To do this, we make use of the Single checkbox flavour which allows you to set conditions based on each checkbox individually.

A scenario is simply a manual grouping of conditions in which some conditions are evaluated independently of other conditions from other scenarios. The complex condition resulting in this association of several scenarios will be met only if one scenario is met. In other words, scenarios are logical grouping of conditions, respecting the above rules, and which are ORed together to build complex conditions.

Everything described above applies to the conditions located in every scenario. By default, all the new conditions are created inside the Default Scenario, which uses number '1' as its identifier. When you create new conditions, you can choose whether they are added to the default scenario or not. To change the scenario, just use another identifier.

To create three scenarios, you need at least three conditions and to add to each of them a different scenario id. Once done, the scenarios are going to be connected among themselves via the 'OR' operator. For example, it could look like this:

The copy conditions functionality can be used when you wish to apply the same set of conditions you applied to Question5 to Question10. In this way, you will not have to manually recreate the conditions you applied to the previous question(s).

To start copying conditions, you first have to select the question the condition(s) is/are applied to (Question 'LowQ' in our case). Then, select the conditions you wish to be copied and select the question you wish to have the conditions added to (Question 'Alcohol' in our case).

Please pay attention to how the copy conditions functions work when you wish to copy and apply a set of conditions located under different scenarios to another question which uses the same or different scenario id numbers. To summarise the possible cases you might have, check the following example:
