Answer 2

Let's break down the expression step by step:

1. Start with the innermost parentheses:

   • (7 - 6) = 1
   • 1 * 2 = 2

2. Replace the innermost parentheses with the result:

   • 2

3. Now, move on to the next set of parentheses:

   • (16:1 - 45 + 2:11 - 3)

4. Calculate the divisions first:

   • 16 ÷ 1 = 16
   • 2 ÷ 11 ≈ 0.1818 (rounded to four decimal places)

5. Now, subtract and add the results within the parentheses:

   • 16 - 45 + 0.1818 - 3 ≈ -31.8182 (rounded to four decimal places)

6. Replace the innermost parentheses with the result:

   • -31.8182

7. Now, we have the expression left:

   • 2 : (-31.8182) * 5 * 28

8. Calculate the division:

   • 2 ÷ (-31.8182) ≈ -0.0627484 (rounded to seven decimal places)

9. Now, multiply the results:

   • -0.0627484 * 5 * 28 ≈ -8.824376 (rounded to six decimal places)

10. Finally, add 1129 to the result:

    • 1129 - 8.824376 ≈ 1120.175624 (rounded to six decimal places)

So, the final result is approximately 1120.175624.
