Question

(—3) × (—5) × (2) ×(4)

Answer 1

Answer:

120 is the answer

Answer 2

To solve : $(-3)\times (-5)\times (2) \times (4)$

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 $(-3)\times (-5)\times (2) \times (4)$  .

              $(-3)\times (-5) \times (2)\times (4 ) = (15 )\times (8 ) = 120$

Hence , $120$ is the product .
