Evaluate:
`(1) times (1) times (1) times (1) times (-1) times (-1) times (-1) times (-1) times (-1) times (-1) times (-1)`

Answer

To evaluate the expression `(1) times (1) times (1) times (1) times (-1) times (-1) times (-1) times (-1) times (-1) times (-1) times (-1)`, we can follow these steps:

### Step 1: Count the number of times each number is multiplied.
- We have `1` multiplied 4 times.
- We have `-1` multiplied 7 times.

### Step 2: Write the expression using exponents.
- The expression can be rewritten as:
\[ 1^4 \times (-1)^7 \]

### Step 3: Evaluate \(1^4\).
- Any number raised to a power is the number multiplied by itself that many times. Since \(1\) multiplied by itself any number of times is still \(1\):
\[ 1^4 = 1 \]

### Step 4: Evaluate \((-1)^7\).
- Since \(-1\) raised to an odd power results in \(-1\):
\[ (-1)^7 = -1 \]

### Step 5: Combine the results.
- Now we multiply the results from Step 3 and Step 4:
\[ 1 \times (-1) = -1 \]

### Final Answer:
The value of the expression is \(-1\).
