Chapter 10 Lists
1.
emptyList = []
lst = [1, 32, 2]
2.
There are 6 elements in the list. The index of the first element is 0. The index of the last
element is 5. lst[2] is 12. list[-2] is list[5-2], which is 14.

If p and q are statement variables,
p -> q :
p: the hypothesis or antecedent
q: the conclusion or consequent

4.5 DIRECT PROOF AND COUNTEREXAMPLE V: FLOOR AND CEILING
Definition
Given any real number x, the floor of x, denoted that
x
= the unique integer n such that n x < n + 1
Symbolically, if x is a real number and n is an integer, then
x
=n
n x<n+1

4.7 THEOREMS
Note that every nonzero rational number has exactly one simplest form of ratio of two integers
with a positive denominator (e.g., 3/6 => 2/4 => 1/2). The simplest form is when the numerator
and the denominator have no common divis
