how to solve this sum(-57)x(-19)x57 Please explain

Question

This is a sum from the chapter multiplication of integers using property

Answer 1

I'm assuming the problem is:

 

(-57)*(-19)*(57)

 

which is a product, not a sum (sum is for addition, not multiplication).  If it's a different problem, please let us know.

 

Just multiply the three numbers together, in any order.  Multiplication obeys the commutative and associative laws, so you can move the numbers around or do them in any order.

 

Try multiplying (-57)*(-19) first.  Then multiply the answer by 57.
