Answer 2

To solve : $20\times 30$

solution:

• Multiplication is a process of repetitive addition of integers.
• Multiplication rules for integers :

1. if two negative integers are multiplied then the product obtained is positive integer. i.e.$(-) \times(-)=+$
2. If one negative and one positive integers are multiplied then the product obtained is negative integer. i.e. $(-) \times(+)=-$
3. If both positive integers are multiplied then the product obtained is positive integer. i.e.$(+) \times(+)=+$

• Therefore according to above rule we solve  

            $20\times 30$ $= 600$

Hence, $600$ is the product.
