Which of the following is not a member of the fact family for 54 - n = 18 - 18 + n = 54
- n + 18 = 54
- 54 - 18 = n
- 18 - n = 54
Which of the following is not a member of the fact family for n - 27 = 23 - 27 - n = 23
- n - 27 = 23
- 23 + 27 = n
- 27 + 23 = n
Which of the following is not a member of the fact family for 38 - 12 = 26 - 26 - 12 = 38
- 12 + 26 = 38
- 26 + 12 = 38
- 38 - 26 = 12
Which of the following is not a member of the fact family for n - 14 = 36 - n - 36 = 14
- 36 + 14 = n
- 36 - n = 14
