Answer 2

To solve the given expression step by step, we'll follow the order of operations: parentheses first, then multiplication and division, and finally addition and subtraction.

1. Solve the expressions within the parentheses: $(-4.4 + 1.8)$ = $-2.6$

2. Now, we have: $8 \times 2.5 - 100 \div (-2.6)$

3. Perform the division first: $100 \div (-2.6) \approx -38.461538$ (rounded to six decimal places)

4. Substitute this back into the expression: $8 \times 2.5 - (-38.461538)$

5. Next, perform the subtraction: $20 - (-38.461538)$ $20 + 38.461538 \approx 58.461538$ (rounded to six decimal places)

So, the value of the expression is approximately $58.461538$ (rounded to six decimal places).
