Answer 2

To solve this mathematical expression, follow the order of operations (PEMDAS/BODMAS):

1. Parentheses/Brackets
2. Exponents/Orders
3. Multiplication and Division (from left to right)
4. Addition and Subtraction (from left to right)

Let's break down the expression step by step:

Given expression: 19 - (128 - ((47 * 29 + 31 * 51) / 46 + 21 * 31) / 55) / 23

1. Calculate the values inside the innermost parentheses:

   • 47 * 29 = 1363
   • 31 * 51 = 1581
   • 1363 + 1581 = 2944
   • 2944 / 46 ≈ 64

2. Continue evaluating the inner parentheses:

   • 21 * 31 = 651
   • 64 + 651 = 715

3. Next, evaluate the remaining inner parentheses:

   • 715 / 55 ≈ 13

4. Evaluate the remaining expression:

   • 128 - 13 = 115

5. Finally, evaluate the entire expression:

   • 19 - 115 = -96

So, the result of the given expression is approximately -96.
