Answer 2

It appears that you've provided a sequence of numbers with some mathematical operations. Let's break down the expression step by step:

1. Starting with the initial numbers:

   • 813

2. Next, we have a series of multiplications and additions:

   • 1.0 * 5 = 5.0
   • 452.0 * 4 = 1808.0
   • 403.0 * 2 = 806.0
   • 94.0 * 8 = 752.0
   • 55.0 * 7 = 385.0
   • 36.0 * 3 = 108.0
   • 257.0 * (1 + 7) = 257.0 * 8 = 2056.0
   • 48.0 * (5 + 3) = 48.0 * 8 = 384.0
   • 39.0 * (6 + 15) = 39.0 * 21 = 819.0
   • 5 * (3 + 5) = 5 * 8 = 40.0

3. Now, we need to add up all these results:

   • 813 + 5.0 + 1808.0 + 806.0 + 752.0 + 385.0 + 108.0 + 2056.0 + 384.0 + 819.0 + 40.0

Let's calculate the final result:

813 + 5.0 + 1808.0 + 806.0 + 752.0 + 385.0 + 108.0 + 2056.0 + 384.0 + 819.0 + 40.0 = 7066.0

So, the final result of the expression is 7066.0.
