Find the product :
`8xx(-15)`

Answer

To find the product of \( 8 \) and \( -15 \), we can follow these steps:

### Step 1: Write down the expression
We start with the expression:
\[ 8 \times (-15) \]

### Step 2: Identify the signs
In this case, we have one positive number (8) and one negative number (-15). According to the rules of multiplication:
- The product of a positive number and a negative number is always negative.

### Step 3: Multiply the absolute values
Next, we multiply the absolute values of the numbers:
\[ 8 \times 15 \]

### Step 4: Perform the multiplication
Now we calculate \( 8 \times 15 \):
- \( 8 \times 5 = 40 \) (write down 0 and carry over 4)
- \( 8 \times 1 = 8 \), and adding the carry 4 gives us \( 8 + 4 = 12 \)

Thus, \( 8 \times 15 = 120 \).

### Step 5: Apply the sign
Since we are multiplying a positive number by a negative number, the product will be negative:
\[ 8 \times (-15) = -120 \]

### Final Answer
The product of \( 8 \) and \( -15 \) is:
\[ \boxed{-120} \]
