Use the distributive property to remove the parentheses. +-33x2y-4

Question

i don't understand the answer

Answer 1

Hello,

 

There should be parentheses and I think they want you to solve it as if there were parentheses.  For example

 

+(-33x2y)-4 in order to remove the parentheses you would use the distributive property, so the answer becomes:

 

-99xy-4.
