Answer 3

To solve this expression, you should follow the order of operations (PEMDAS/BODMAS), which stands for Parentheses/Brackets, Exponents/Orders (i.e., powers and square roots, etc.), Multiplication and Division (left-to-right), and Addition and Subtraction (left-to-right).

Here's the step-by-step calculation for your expression:

1. First, perform the multiplication and division from left to right:

   5 + 5/7 + 4/5 + 2 - 78410 - 115 = 5 + 0.71428571 + 0.8 + 2 - 78410 - 115 (5 divided by 7 is approximately 0.71428571, and 4 divided by 5 is 0.8)

2. Now, perform the multiplications:

   5 + 0.71428571 + 0.8 + 2 - 78*410 - 115 = 5 + 0.71428571 + 0.8 + 2 - 31980 - 115 (78 multiplied by 410 is 31980)

3. Finally, perform the additions and subtractions:

   5 + 0.71428571 + 0.8 + 2 - 31980 - 115 = -31171.48571429

So, the result of the expression is approximately -31171.49 (rounded to two decimal places).
