Explanation:

Question 2

Step1: Calculate A: \(52 + 17\)

\(52 + 17 = 69\)

Step2: Calculate B: \(45 + 24\)

\(45 + 24 = 69\)

Step3: Calculate C: \(92 - 21\)

\(92 - 21 = 71\)

Step4: Calculate D: \(84 - 18\)

\(84 - 18 = 66\)

Step1: Calculate \(69 + 29\)

\(69 + 29 = 98\)

Step2: Calculate \(96 - 16\)

\(96 - 16 = 80\)

Step3: Calculate \(56 + 32\)

\(56 + 32 = 88\)

Step1: Add 35 and 52

\(35 + 52 = 87\)

Answer:

C. \(92 - 21 =\)
