Answer 2

To solve the given expression, let's break it down step by step:

Step 1: Evaluate the expressions inside the parentheses. - 80 × 8 = 640 - 420 ÷ 7 = 60

The expression becomes: (640 + 60) ÷ 100 + ...

Step 2: Continue evaluating the expression inside the parentheses. - 140 ÷ 20 = 7 - 38 ÷ 19 = 2

The expression becomes: (640 + 60) ÷ 100 + (7 + 2) × 3 = ...

Step 3: Evaluate the addition and multiplication. - (640 + 60) = 700 - (7 + 2) = 9 - (9 × 3) = 27

The expression becomes: 700 ÷ 100 + 27 = ...

Step 4: Evaluate the division and addition. - 700 ÷ 100 = 7 - 7 + 27 = 34

Therefore, the solution to the given expression is 34.
