It also includes producing new propositions using existing ones. The area of logic which deals with propositions is called propositional calculus or propositional logic. By Convention, these variables are represented by small alphabets such as. To represent propositions, propositional variables are used. The above sentences are not propositions as the first two do not have a truth value, and the third one may be true or false. Some sentences that do not have a truth value or may have more than one truth value are not propositions. The sun rises in the East and sets in the West.Īll of the above sentences are propositions, where the first two are Valid(True) and the third one is Invalid(False). The Truth Value of a proposition is True(denoted as T) if it is a true statement, and False(denoted as F) if it is a false statement.ġ. It is defined as a declarative sentence that is either True or False, but not both. Propositional LogicĪ proposition is the basic building block of logic.

These rules are used to distinguish between valid and invalid mathematical arguments.Īpart from its importance in understanding mathematical reasoning, logic has numerous applications in Computer Science, varying from design of digital circuits, to the construction of computer programs and verification of correctness of programs. The rules of logic give precise meaning to mathematical statements. Which in Simple English means “There exists an integer that is not the sum of two squares”. These rules help us understand and reason with statements such as – such that where The rules of logic specify the meaning of mathematical statements. Logic is the basis of all mathematical reasoning, and of all automated reasoning.

This list is meant to be a sub-set of those that I use on a daily basis. I know there are a lot of pages out there that list shortcut keys, but they seem to be huge and also list a ton that I’ll never use. When I found out what the symbols meant, I was able to come up with the following table of the shortcut keys that help me navigate and use Xcode 4 quickly. A quick search led me to Ted Wise’s page:, which was very helpful. However, the option symbol and the control symbol are not on their respective keys so I had to ask Google about them.

Now on the MacBook Pro that I’m currently using, the command symbol is on the command key, so it’s easy to see that the symbol goes with that key. The most notable ones are the control, option and command symbols.

The first confusing thing that I ran into was the funny symbols the Mac OS uses to define special keys. However if I want to do that, I need to know all the keyboard commands that I normally use on a Microsoft Windows computer. In order to do things faster, I try to keep from going back and forth between the keyboard and the mouse.

I’ve never been a Mac user and probably never will be, but since I have to use it for now, it’s really helpful to know how to get around on one. I’ve been tasked with creating a new program to go onto the Apple Store.
