(a)
Answer
Equals (b) 73 - (14 - 1) and (c) 73 + (-14 + 1). Value = 60.
(b)
Answer
Equals (a) 73 - (14 + 1) and (d) 73 + (-14 - 1). Value = 58.
Explanation
(a) 73 - 14 + 1 = 60. (b) 73 - (14 - 1) = 73 - 13 = 60. (c) 73 + (-14 + 1) = 73 - 13 = 60. (b) 73 - 14 - 1 = 58. (a) 73 - (14 + 1) = 73 - 15 = 58. (d) 73 + (-14 - 1) = 73 - 15 = 58.
