Take a few more examples of multiplication of 3 integers and check this property. Class 7

Question 1.

Take a few more examples of multiplication of 3 integers and check this property. What do you observe? Class 7

Solution:

Do as directed. For example,

(6 × (-3)) × (-8) = -18 × (-8) = 144 and

6 × ((-3) × (-8)) = 6 × 24 = 144 Product will remain the same.

Question 2.

Are there orders in which 5 × - 3 × 4 can be evaluated? Will the product be the same in all these cases? Class 7

Solution:

Yes, yes.

Question 3.

Multiply the expression 25 × - 6 × 12 in all the different orders and check if the product is the same in all cases. Class 7

Solution:

25 × (-6) × 12 = -150 × 12 = - 1800

25 × (-6) × 12 = 25 × (-72) = - 1800

25 × 12 × (-6) = 300 × (-6) = - 1800

Yes.
