Question

3.58 - (-5.23)\
-7.56 + 9.258\
-7.23 - 19.56

Explanation:

Step1: Simplify \( 3.58 - (-5.23) \)

Subtracting a negative is adding the positive, so \( 3.58 - (-5.23)=3.58 + 5.23 \).
Calculating the sum: \( 3.58+5.23 = 8.81 \).

Step2: Simplify \( -7.56 + 9.258 \)

Subtract the smaller absolute value from the larger: \( 9.258 - 7.56 = 1.698 \).
Since \( 9.258 \) is positive, the result is \( 1.698 \).

Step3: Simplify \( -7.23 - 19.56 \)

Adding two negatives: \( -(7.23 + 19.56) \).
Calculating the sum inside the parentheses: \( 7.23+19.56 = 26.79 \).
So the result is \( -26.79 \).

Answer:

\( 3.58 - (-5.23)=8.81 \), \( -7.56 + 9.258 = 1.698 \), \( -7.23 - 19.56=-26.79 \)
