Answer 2

Calculation: (20 + 9) * 3 = (70 + 21) : 7 = ?

To solve this calculation, we can follow the order of operations (PEMDAS/BODMAS) and perform the operations step by step.

Step 1: Calculate the sum inside the parentheses: (20 + 9) = 29. Step 2: Multiply the result by 3: 29 * 3 = 87. Step 3: Calculate the sum inside the second set of parentheses: (70 + 21) = 91. Step 4: Divide the second result by 7: 91 / 7 = 13.

Therefore, the final result is 13.

Answer: 13
