Question

-3,5-(5,2-(1,2+(-0,4+2)))

Answer 1

2-0,4=1,6

1,6+1,2=2,8

5,2-2,8=2,4

-3,5-2,4=-5,9

Answer 2

-0.4+2=1.6
1,2+1,6=2,8
5,2-2,8=2,4
-3,5-2,4= -5,9
-3,5-(5,2-(1,2+(-0,4+2)))= -5,9

Answer 3

To solve this expression, you should follow the order of operations, which is typically referred to as PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction).

Let's break it down step by step:

1. Start with the innermost parentheses:

   • Inside the innermost parentheses: (-0.4 + 2) = 1.6 So now we have: -3.5 - (5.2 - (1.2 + 1.6))

2. Next, calculate the addition inside the next set of parentheses:

   • (1.2 + 1.6) = 2.8 So now we have: -3.5 - (5.2 - 2.8)

3. Now, calculate the subtraction inside the next set of parentheses:

   • (5.2 - 2.8) = 2.4 So now we have: -3.5 - 2.4

4. Finally, calculate the subtraction:

   • (-3.5 - 2.4) = -6.9

So the result of the expression -3.5 - (5.2 - (1.2 + (-0.4 + 2))) is -6.9.
