Study Guide for Test 1 (03 Oct 2012)

* There will be conversions of decimal numbers into binary, 
  octal, and hexadecimal and vice versa.

* There will be conversions of negative numbers into 8-bit 
  2's complement numbers. 

* You will create truth tables for Boolean expressions that will
  involve Boolean operators not, and, or, xor. The Boolean expressions
  will involve just two Boolean variables (let us say A and B) and your
  truth tables will have all possible permutations of A and B.

* You will define variables, i.e. write meaningful variable names and
  their values.

* You will evaluate expressions given certain input values. This will
  involve all the operators that were discussed in class.

* You will write Boolean expressions that evaluate to True
  given a set of conditions.

* There will be questions on conditionals. You will either write 
  conditional statements given a set of criteria or you will
  be given a conditional statements and a set of input values and
  you should be able to state what the result or output of those
  conditionals will be.

* You will write simple loops using while and for. You should know
  when and how to use break and continue.

* You are responsible for these built-in functions:
  - abs (x)
  - chr (i)
  - float (x)
  - int (x)
  - len (s)
  - long (x)
  - ord (c)
  - range ([start], stop [, step])
  - str (object)

* You are responsible for these math functions:
  - math.fabs()
  - math.ceil()
  - math.floor()
  - math.sqrt()
  - math.degrees()
  - math.radians()

* You will have to write a full length program that will involve
  user input, computations, conditionals, loops and formatted
  output.
