Answer 2

To calculate the expression:

(2.3 × (-1.8) - 1.4 × (-0.8)) × (-1.5)

Let's break it down step by step:

Step 1: Multiply the values inside the parentheses:

2.3 × (-1.8) = -4.14 1.4 × (-0.8) = -1.12

The expression becomes:

(-4.14 - (-1.12)) × (-1.5)

Step 2: Simplify the subtraction:

(-4.14 + 1.12) × (-1.5)

Step 3: Perform the addition:

-4.14 + 1.12 = -3.02

The expression becomes:

-3.02 × (-1.5)

Step 4: Multiply the values:

-3.02 × (-1.5) = 4.53

Therefore, (2.3 × (-1.8) - 1.4 × (-0.8)) × (-1.5) equals 4.53.
