Answer 2

Let's break this down step by step, following the order of operations (PEMDAS):

1. Perform any calculations inside parentheses first.

There are no parentheses in the expression.

2. Evaluate exponents.

There are no exponents in the expression.

3. Perform multiplication and division, from left to right.

2005 × 8 = 16040

6400 ÷ 800 = 8

16040 - 704 × 21 + 8 = -12996

4. Perform addition and subtraction, from left to right.

702 × 860 = 604920

604920 - 603704 = 1216

-12996 ÷ 1216 ≈ -10.68

Therefore, the final answer is approximately -10.68.
