Logical Reasoning and Intelligence Systems
The lesson covers the meaning of simple and compound statements. It explains five logical operations and their symbols, along with truth values of compound statements. The lesson also discusses the equivalence of contra-positives and converses in conditional statements, and introduces the concept of
- 30:52 “this one, the p, give us the conclusion of this, and between this, therefore there is also give us q, so we can also represent it in this form, and we can easily construct the true table for this, and the true table for...”
- 19:56 “only Q, Lagos is true, whereas the rest are false, because A, Q, Lagos is both components of the position are true, where others, provision at least, one component of each provision is false, a true table of however we a...”
- 20:45 “meaning that a true table can also be used to, to test the validity of, of, of, of, of any statement, so the following are the true table for negation, conjunction, and discussion, so we have if P is a statement, and if...”
Logical Statements and Negation
This lesson covers the definition of logical statements and how to identify true and false statements. It explains negation, conditional statements, and the antecedents of statements with examples.
- 00:49 “false, but not both. It means any statement that is logical. It is either true or false, but cannot be true and as well a false. That is what it means. So your statements can either be true or false, but cannot be true a...”
- 04:12 “Now if P is true, that is if the statement P is true, the negation of that is going to be what is going to be false and we know we said a true statement or a logical statement is going to be noted by C and the false stat...”
- 23:25 “Mary is a model, she's beautiful, have different true values. We understand it at all. So that is how to represent a background statement in a true or falseity table. Now have understood what we mean by logical statement...”
Introduction to Operations Research
This lesson defines operations research and explains its application in management, industry, and business. It covers the steps involved in solving problems using mathematical models and discusses different types of models used in operations research.
- 26:13 “to give out the same number, if deduct 0 is the list number as well, and the list number here is 1, so we minus 1 from this, 4 minus 1, that will give us 3, 2 minus 1, that will give us 1, 1 minus 1, give us 0, 2 minus 1...”
- 25:23 “and the fourth row also has at least 1, 0 entry, now let's look at the column as well, the column has at least 1, 0 entry, the second column also has at least 1, 0 entry, at least 1, 0 entry, it can't be 2, but the last...”
- 24:32 “we have here is 6, so we subtract 6 from here, we subtract 6 from here, we subtract 6 from here, we subtract 6 from here, the list number we have here is 5, we subtract 5 from here, we subtract 5 from here, we subtract 5...”
