Answer 3

Let's break down the expression step by step:

1. First, perform the addition and subtraction within the parentheses: 2.3 + 5 = 7.3 220 - 30 = 190 101 - 100 = 1

2. Now, let's continue with the multiplication and division: (7.3 * 5.2) = 37.96 (247 - 240) = 7 (190 * 0) = 0 (1 / 749994.2) ≈ 1.33333e-06

3. Finally, perform the remaining additions and subtractions: 1000 - 37.96 + 0 + 1.33333e-06

Now, add and subtract these values:

1000 - 37.96 + 0 + 1.33333e-06 ≈ 962.040001

So, the result of the expression is approximately 962.040001.
