- Boolean algebra is the modern digital computer logic that was developed by English mathematician George Boole in the 1840's. (Source: http://en.wikipedia.org/wiki/George_Boole)

- This type of algebra system is intended to enable humans like us to communicate with computers using different number systems to input logical statements using these numerical symbols.

- In boolean algebra, AND means X in terms of regular algebra. For example: A AND B is equal to A*B or AB.

- In boolean algebra, OR means + in terms of regular algebra. For example: A or B is equal to (A) or (B).

- In boolean algebra, inverters refer to switching a letter such as A into a letter with a bar on top such as A(bar).

- In computers, we use a hexadecimal system based on a base of 16 such as 16^5, 16^4, 16^3, 16^2, 16^1, and 16^0.

- The numbers of a hexadecimal system is 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, and F. For example, the number 16 is converted in a hexadecimal system to (1, 0) which is equal to 16^1 + 0, which is 16.

- In computers, there are 8 bits for every byte.

- There is another system used in computers as well and that is the binary number system.

- In the binary system, the only numbers used are 1 and 0. For example: 2 is equal to (1, 0) which is equal to 2^`1 + 0.

- These number systems are used to provide a logic that can be used to communicate with robots and computers that can enable them to perform various tasks.
