Answer 2

Solving the Expression 4.2 - (5.2 - 3.8)

To solve the expression 4.2 - (5.2 - 3.8), we'll follow the order of operations, which is parentheses first, then multiplication and division (from left to right), and finally addition and subtraction (from left to right).

First, we'll solve the expression inside the parentheses, and then subtract that result from 4.2.

Solution Steps:

1. Solving the Expression Inside the Parentheses: - 5.2 - 3.8 = 1.4

2. Subtracting the Result from 4.2: - 4.2 - 1.4 = 2.8

Therefore, the value of the expression 4.2 - (5.2 - 3.8) is 2.8.
