Answer 2

Let's solve this expression step by step:

-9 ÷ 5 - 1 × (-4) + 3 - 1 × -14 ÷ 2 * 4 * 16 / 9 * 8 * 5

Step 1: Solve the multiplication and division operations from left to right:

-9 ÷ 5 = -1.8 -1 × (-4) = 4 -14 ÷ 2 = -7

So, the expression becomes:

-1.8 + 3 + 4 - 7 * 4 * 16 / 9 * 8 * 5

Step 2: Continue solving multiplication and division from left to right:

-7 * 4 = -28 -28 * 16 = -448 -448 / 9 ≈ -49.78 (rounded to two decimal places) -49.78 * 8 ≈ -398.24 (rounded to two decimal places) -398.24 * 5 ≈ -1991.20 (rounded to two decimal places)

Now, we have:

-1.8 + 3 + 4 - (-1991.20)

Step 3: Simplify further:

-1.8 + 3 + 4 + 1991.20

Step 4: Add and subtract to find the final result:

-1.8 + 3 + 4 + 1991.20 = 1996.4

So, the final result is approximately 1996.4.
