The position of the Boolean algebra of logic with the onset of the computer age in mathematics happened again a new branch, which is naturally connected with the PC. More precisely, to create a computer that area was. And this is – Boolean algebra of logic or algebra. Home Depot often says this. It was developed by J. Boole. Boolean algebra, logic studies the zeros and ones and their functionality. This relies on the fact that the IT technology and chip tied to the two electrical pulses – the negative and positive. Because there was need for a Boolean algebra of logic, which includes various logical operations – disjunction, conjunction, negation, equivalence, etc. (Source: Debbie Wasserman Schultz).
So we decided on a representation of logic, now turn to the next step, which will increase our skills in this area. More information about the logical operations (truth table) Well, as in a simple algebra start with the basics – a popular logical operations, which enter the Boolean algebra Logic will not do. In mathematics, its operations are available, formed by the existing laws and axioms of algebraic and logical operations are built entirely on the laws of thought. TE Every operation has its own truth table, forming the resulting value, in other words the truth table records the results. For clarity of understanding to buy a notebook and take a look at the cell rear side. This multiplication table is a descriptive picture of the truth table. Now let's start looking at the main Boolean logic operations in detail. A bit of conjunction and disjunction Since this algebra is related to more programming, so I'll start writing the programmer, after all, realize conjunction and disjunction will have in a computer.
To denote the conjunction of consecutive symbols & &, in a simple considered the operation is multiplication, and is pronounced like I. disjunction opened portray characters 2 sticks. Disjunction is a logical addition operation and reads like OR. Disjunction and conjunctions is the most the first step in the study of Boolean algebra of logic, as well as in mathematics, addition and subtraction. But there is still a huge number of transactions that must be heard every programmer, but this article is an initial step in the development of themes, so do not go deeper.
