Final answer:
The question involves evaluating a complex fraction expression using the order of operations. The PEMDAS rule is applied, taking care to correctly interpret the subtraction of negative numbers and division within the expression.
Step-by-step explanation:
The question asks to evaluate the mathematical expression -(2/5)+(-(3/5)--(1/2))-:-(1/3). To solve it, we have to follow the order of operations, also known as PEMDAS (Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction). Here's how we can break it down:
- First deal with the subtraction and addition inside the brackets, remembering to change the sign when subtracting a negative, which is equivalent to addition.
- Then perform the division indicated by the division symbol (:).
- Finally, combine all the results to find the overall value of the expression.
Note that typos in the original problem can alter the intended meaning of the expression, so care must be taken to interpret it correctly.
