Final answer:
To solve the expression, the order of operations was followed, starting with the innermost brackets, then the curly braces, and finally the entire expression. The result of the expression is 1.
Step-by-step explanation:
The arithmetic operation in question involves the use of negative numbers and the order of operations, commonly known as PEMDAS or BIDMAS, which stand for Parentheses/Brackets, Exponents/Indices, Multiplication, Division, Addition, and Subtraction. Let's solve the expression step-by-step:
- Start by solving the innermost brackets: [(−7) + (−3) - (−8)] = -7 - 3 + 8 = -10 + 8 = -2.
- Next, solve the subtraction within the curly braces: (−5) - (-2) = -5 + 2 = -3.
- Finally, solve the entire expression: (−4) - (−2) - (-3) = -4 + 2 + 3 = 1.
The result of the expression is 1.
