Question

While multiplying a positive integer and a negative integer, we multiply them as ________ numbers and put a ________ sign before the product. Fill in the blanks to make the statement true.

• A. whole
• B. negative

Answer 1

Explanation.

In the case of multiplication of integers, just multiply the numbers without the sign.

After the product is obtained give the sign according to the rule of multiplication as

$$\begin{gathered} \left(+\right)\times \left(+\right)=+ \\ \left(+\right)\times \left(-\right)=- \\ \left(-\right)\times \left(+\right)=- \\ \left(-\right)\times \left(-\right)=+ \end{gathered}$$

Hence, while multiplying a positive integer and a negative integer, we multiply them as whole numbers and put a negative sign before the product.
