Problem 42 - Elementary Algebra

Question

Rewrite the problem in a simpler form. $$ -\\{-[-(-31)]\\} $$

Step-by-Step Solution

Answer

Question: Evaluate the expression -(-(-31)). Answer: -31

Step 1: Evaluate the innermost parentheses

In this case, we are asked to evaluate -(-31). The negative sign negates the value inside the parentheses, changing it to a positive value. So, we have: $$ -[-(31)] $$

Step 2: Evaluate the next set of parentheses

Now we have -[(31)], and once again, we have to negate the value inside the parentheses. Therefore, we have: $$ -(31) $$

Step 3: Final simplification

Finally, negating 31 gives us the final expression: $$ -31 $$
