- On page 53 of the Student Workbook, Problem 2.10, line 3: "remember we learned a technique to do this calculations quicker!" Here "this" should be "these".
- On page 32 of the Solutions book, Problem 2.10, bottom line: same error as above.
- On page 58 of the Student Workbook, Problem 2.17, line 3: "strategry" should be "strategy".
- On page 38 of the Solutions book, Problem 2.17, line 3: same error as above.
- On page 93 of the Student Workbook, the end of the solution for Example 4.3 should read "Nathan is 56 ÷ 2 = 28 years old, and Matt is 28 - 6=22 years old."
- On page 184 of the Student Workbook, Problem 7.28, "Jing and Xin" should be "Jing and Xing".

- On page 86 of the Student Workbook, Problem 3.25, "originally had the number of" should be "originally had the same number of".
- On page 68 of the Solutions book, Problem 3,25, same error as above.
- Problem 6.33 part (f), answer "1,1,3,5,8,13,..." should be "1,1,2,3,5,8,13,..."
- On page 99 of the Solutions book, Problem 5.25, "There are 26 - 4 = 21 letters" should say "There are 26 - 5 = 21 letters"
- On page 101 of the Solutions book, Problem 5.21, solution is not displayed. Should say "John could use 0, 1, 2, 3 or 4 M$3 bills, and 0, 1, 2, or 3 M$5 bills. So, he can choose to use M$3 bills in 5 ways and M$5 bills in 4 ways. This means he has 5 x 4 = 20 ways of choosing which bills to use. However, since he will use at least 1 bill, John can't choose to use 0 M$3 bills and 0 M$5 bills at the same time. Therefore the final answer is 20 -1 = 19".
