Step-by-Step Solution

Answer

The product of the expression is 105.

The product of two integers with the same sign is always positive 

The product of two integers with opposite signs is always negative 

Step 2. For example.

If –x is multiplied by –y then their product will be xy.

Step 3. Calculate the product.

$\begin{array}{l}\underset{¯}{\begin{array}{l}-21\\ \times -5\end{array}}\\ \text{ 105}\end{array}$

Therefore, the product of the given expression is 105.
