Answer 3

To calculate the expression (-9 × 4) × (2.5), you need to follow the order of operations, which is commonly known as PEMDAS (Parentheses, Exponents, Multiplication and Division from left to right, and Addition and Subtraction from left to right).

Let's break down the calculation step by step:

1. Start with the parentheses: (-9 × 4) equals -36. The expression now becomes: -36 × (2.5).

2. Next, perform the multiplication: -36 × 2.5 equals -90.

Therefore, the result of the expression (-9 × 4) × (2.5) is -90.
