Find the following product :
`15xx(-13)`

Answer

To find the product of \( 15 \) and \( -13 \), we can follow these steps:

### Step 1: Multiply the absolute values of the numbers
We first ignore the signs and multiply the absolute values of the numbers:
\[ 15 \times 13 \]

### Step 2: Perform the multiplication
Now we will calculate \( 15 \times 13 \):
- Break it down:
- \( 15 \times 3 = 45 \) (This is the unit place multiplication)
- \( 15 \times 10 = 150 \) (This is the tens place multiplication)

Now, add these two results together:
\[ 45 + 150 = 195 \]

### Step 3: Determine the sign of the product
Now we need to consider the signs of the original numbers:
- The first number \( 15 \) is positive.
- The second number \( -13 \) is negative.

According to the rules of multiplication:
- Positive multiplied by negative results in a negative product.

Thus, we have:
\[ 15 \times -13 = -195 \]

### Final Answer
The product of \( 15 \) and \( -13 \) is:
\[ -195 \]
