Page	Loc	Description	Erroneous Text	Correction
48	Bot	The second-to-last sentence on the page is from another source and should be entirely ignored.	“It is patently unfair that men avoid the rewards of unwanted fatherhood by presuming that their judgement over such matters is more valid than the judgment of the General Assembly.”
94	Bot	In the chart at the bottom of the page, the bottom-right box should say 3^1, NOT 3^2 (because 12 is only divisible by 3 one time).
83	Top	In the explanation for #1, the explanation writes 5^x instead of 5^z.	You can break the bases into prime factors: (2 * 5)^x = (2^2)^y * 5^x = 2^2y * 5^x	You can break the bases into prime factors: (2 * 5)^x = (2^2)^y * 5^z = 2^2y * 5^z
109	Top	The explanation for statement 2 makes a mistake./	For example, if x = 1 and y = 5, then the GCF is 1.	For example, if x = 5 and y = 1, then the GCF is 1.
27	Mid	Instructions mistakenly refer to questions #13-15, as opposed to #7-9.
78	Bot	The explanation for Roman Numeral I should reference Scenario 2, NOT Scenario 1.	a + c is odd: Scenario 1 goes against this statement.	a + c is odd: Scenario 2 goes against this statement.
56	Top	The explanation for #5 mistakenly states that the order in which the soloists appear is important.	In this problem, the order in which the soloists appear is important. Therefore, the problem can be modeled with anagrams of the “word” 12345NNNNN, in which each number represents the page on which a soloist might appear.	In this problem, the order in which the soloists appear is NOT important. Therefore, the problem can be modeled with anagrams of the “word” YYYYYNNNNN:
94	Bot	In the second sentence of the second-to-last paragraph, 32 should be 3^2.	“The 32 factor in the LCM…”	“The 3^2 factor in the LCM…”
125	Mid	In the explanation for #5, the fourth row of the table should read B2, B3, NOT B1, B3.
