Answer 2

Let's break down and calculate each expression step by step:

1. 60 + (12 * 9 - 350 / (7 * 2))

   First, calculate the expression inside the parentheses: 12 * 9 = 108 7 * 2 = 14 350 / 14 = 25

   Now, substitute the results back into the original expression: 60 + (108 - 25)

   Next, calculate the expression inside the inner parentheses: 108 - 25 = 83

   Now, substitute the result back into the original expression: 60 + 83

   Finally, calculate the sum: 60 + 83 = 143

2. 9 * 8 - (42 / 3 + 21) / 7

   First, calculate the expression inside the inner parentheses: 42 / 3 = 14 14 + 21 = 35

   Now, substitute the result back into the original expression: 9 * 8 - 35 / 7

   Next, calculate the expression inside the inner parentheses: 35 / 7 = 5

   Now, substitute the result back into the original expression: 9 * 8 - 5

   Finally, calculate the subtraction: 9 * 8 - 5 = 72 - 5 = 67

So, the final results are:

1. 60 + (12 * 9 - 350 / (7 * 2)) = 143
2. 9 * 8 - (42 / 3 + 21) / 7 = 67
