Page	Location	Description	Erroneous Text	Correction
40	Top	#8, first line of solution, right of the colon.  Subsequent calculations are correct.	[11 – 3(x + 4)] / (x – 3) = 7	[11 + 3(x + 4)] / (x – 3) = 7
45	Middle	#4, 2nd line of solution	((4 + 8)/(2 + 4)) – (4 + 8 ÷ 2 + 6)	((4 + 8)/(2 + 6)) – (4 + 8 ÷ 2 + 6)
84	Middle	Typo	Note: There are have two possible values for y.	Note: There are two possible values for y.
95	Top	#27, GT and LT notation can be confusing when multiplying with negatives.	Extreme values for a are greater than –4, or GT(–4), and less than 4, or LT(4).  Extreme values for b are greater than –2 or GT(–2), and less than –1, or LT(–1).	Extreme values for a are greater than –4 and less than 4.  Extreme values for b are greater than –2 and less than –1.
95	Top	#27, GT and LT notation can be confusing when multiplying with negatives.	The most negative ab can be is GT(–2) × GT(4) = GT(–8). The most positive ab can be is GT(–4) × LT(–2) = LT(+8).	The most negative ab can be is (less positive than 4) × (less negative than –2) = less negative than –8. The most positive ab can be is (less negative than –4) × (less negative than –2) = less positive than 8.
