Answer 1

28,3-1,8+6-18,2+11,7=26

Answer 2

To solve the expression 28.3 + (-1.8 + 6) - (18.2 - 11.7) with the distribution of parentheses, we can follow the order of operations, which is commonly known as PEMDAS (Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction).

Let's break down the expression step by step:

1. Start by solving the expression inside the parentheses: -1.8 + 6 = 4.2.

2. Now, we can rewrite the expression as: 28.3 + 4.2 - (18.2 - 11.7).

3. Next, solve the expression inside the second set of parentheses: 18.2 - 11.7 = 6.5.

4. Now, we can rewrite the expression as: 28.3 + 4.2 - 6.5.

5. Finally, perform the addition and subtraction from left to right: 28.3 + 4.2 = 32.5, and 32.5 - 6.5 = 26.

Therefore, the solution to the expression 28.3 + (-1.8 + 6) - (18.2 - 11.7) with the distribution of parentheses is 26.
