use properties to find the sum or product.
89+27+11

Ok, Josh! So, first, ask yourself, what are they asking?  They are asking to use properties to find the product, of course! Now, think of what you are doing out of addition, subtraction, multiplication, and division. That was easy. Addition! So you need to find the sum. Obviously that was the easy part. We need to add the smaller numbers first. So:
 
              27 + 11 = Y (Y will be the answer that you will find.
              Then you would add:
                Y + 89 = X (X = the final answer) 
I hope I helped! :D

20y5 times 2 is 1010 times -2 is -20, plus y
