Answer 1

27,54-32+49-15,61=28,79
34,79-48+29,3-54=-37,91
-72+59,1-44,7+62=4,4

Answer 2

Task A: (27.54 - 32) - (-49 + 15.61)

To solve this expression, 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 with the innermost parentheses: (-49 + 15.61) = -33.39. 2. Now substitute the result back into the original expression: (27.54 - 32) - (-33.39). 3. Perform the subtraction inside the first set of parentheses: 27.54 - 32 = -4.46. 4. Substitute the result back into the expression: -4.46 - (-33.39). 5. To subtract a negative number, we can change it to addition: -4.46 + 33.39 = 28.93.

Therefore, the value of (27.54 - 32) - (-49 + 15.61) is 28.93.

Task B: (34.79 - 48) - (-29.3 + 54)

Let's solve this expression step by step:

1. Start with the innermost parentheses: (-29.3 + 54) = 24.7. 2. Now substitute the result back into the original expression: (34.79 - 48) - 24.7. 3. Perform the subtraction inside the first set of parentheses: 34.79 - 48 = -13.21. 4. Substitute the result back into the expression: -13.21 - 24.7. 5. Perform the subtraction: -13.21 - 24.7 = -37.91.

Therefore, the value of (34.79 - 48) - (-29.3 + 54) is -37.91.

Task C: (-72 + 59.1) + (-44.7 + 62)

Let's solve this expression step by step:

1. Start with the innermost parentheses: (-72 + 59.1) = -12.9 and (-44.7 + 62) = 17.3. 2. Now substitute the results back into the original expression: -12.9 + 17.3. 3. Perform the addition: -12.9 + 17.3 = 4.4.

Therefore, the value of (-72 + 59.1) + (-44.7 + 62) is 4.4.
