Answer 1

17,8-(11,7+14,8)-(3,5-12,6)=17,8-26,5+9,1=0,4

Answer 2

1)11,7+14,8=26,5
2)12,6-3,5=9,1
3)26,5-17,8=8,7
4)9,1-8,7=0,4

Answer 3

To solve the expression, we need to follow the order of operations, which is often remembered using the acronym PEMDAS:

P - Parentheses (or Brackets) E - Exponents (or Powers) MD - Multiplication and Division (left-to-right) AS - Addition and Subtraction (left-to-right)

Let's solve the expression step by step:

1. Calculate the expression inside the parentheses first:

11.7 + 14.8 = 26.5 3.5 - 12.6 = -9.1

2. Now, the expression becomes:

17.8 - (26.5) - (-9.1)

3. Perform the subtraction inside the parentheses:

17.8 - 26.5 = -8.7

4. The expression now becomes:

-8.7 - (-9.1)

5. When subtracting a negative number, it is the same as adding its positive counterpart:

-8.7 + 9.1 = 0.4

So, the result of the expression is:

17.8 - (11.7 + 14.8) - (3.5 - 12.6) = 0.4
