Question

What is -42+8.1 x (-1.9)

Answer 1

The question involves basic arithmetic and order of operations (PEMDAS). According to PEMDAS, multiplication should be done before addition. Thus, -42+8.1 x (-1.9) equals -57.39.

Step-by-step explanation:

This problem involves basic arithmetic and the use of the order of operations. The order of operations is often remembered by the acronym PEMDAS which stands for Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).

Applying it to the equation: -42 + 8.1 x (-1.9). According to PEMDAS, we should first perform the multiplication: 8.1 x (-1.9) equals -15.39. Now our equation is -42 -15.39. Adding these numbers together gives us -57.39. So, -42+8.1 x (-1.9) equals -57.39.
