Page 16, section 1.1.5, second bullet point:
"To graph y= 21.5x– 141.7 quickly, press [Y=] and then [5][>][>][1] to paste the RegEQ into Y1."
There should be a "[VARS]" before "[5]"

Page 21, section 1.3, figure 1.18 caption:
"On the left, pressing [2nd][Y=] through [2nd][TRACE] to access context menus."
Both "[2nd]"s should be "[ALPHA]"

Page 43, section 2.4.1, under Finding the Lowest Common Multiple of Two Numbers:
"the lowest common multiple (LCM) of two numbers a and b[...]"
"b" should be italicized as "b"

Page 103, section 4.4.2:
"Look at figure 4.26 for an example of storing a matrix to a list[...]"
"to a list" should be "to a matrix variable"

Page 190, section 8.8.3:
The discussion of the Q1 and Q3 values in points 4 and 5 of the ordered list are incomplete. It must be clarified
that the median is omitted from picking the middle value for Q1 and Q3, and if there are an even number of
elements above or below the median, the average (arithmetic mean) of the two middle values is used.
By this same logic, the Q1 and Q3 values presented in the paragraph immediately following are incorrect. Q1 should
be the average of 1 and 2, or 1.5, and Q3 should be the average of 10 and 20, or 15.

Page 144, section 6.1.2, second paragraph:
"In other words, whenever b2 is larger than 4ac, the Quadratic Formula will yield complex roots."
"larger than" should be "less than."
