Binary, Logic, Etc...

The following is an outline of our study thus far of logic as it pertains to computer programming.

• How to use an abacus -- first in base 10, then in base 2 or binary.
• Addition and subtraction in binary.
• Syllogisms and logic
• Boolean logic: propositional symbols, which show whether a statement is true or false.
• Expanding these true/false tables to show combinations of statements.
• Operators: "and," "or," "not," and "xor" functions are ways to use these tables.
• Put together, these operators can become logical circuits.
• The true/false logic can also be represented as 1 and 0, as in binary, or as on or off, as in a switch of electricity. This technology is what made computers possible, shortly after Vannevar Bush made his predictions about the storing of information (see readings.)
