Answer 2

To calculate the expression 2.1 * (-4.5) * 0.14 * (-0.6) - 1.2 * (-0.49) * 0.9, you can follow these steps:

1. Multiply the numbers within each set of parentheses.
2. Perform the multiplications and subtractions according to the order of operations (PEMDAS/BODMAS: Parentheses/Brackets, Exponents/Orders, Multiplication and Division (left to right), Addition and Subtraction (left to right)).

Here's the calculation step by step:

1. Inside the first set of parentheses: 2.1 * (-4.5) = -9.45
2. Inside the second set of parentheses: 0.14 * (-0.6) = -0.084
3. Inside the third set of parentheses: -1.2 * (-0.49) = 0.588
4. Now, we have the values from steps 1, 2, and 3: -9.45 * -0.084 - 0.588 * 0.9
5. Calculate the products: 0.7938 - 0.5292
6. Finally, subtract the two results: 0.7938 - 0.5292 = 0.2646

So, the result of the expression is approximately 0.2646.
