yes but explain how to do it please step by step

ok, let's try this example: -2(-6)

 

Let's split this into its parts. (-1*2)*(-1*6)

 

We see that there are two negative 1s in this equation, so let's multiply those by each other. -1*-1=1, so we have 1*2*6.

 

Let's combine like terms now. 1*2=2, then multiply 2*6 to get 12. The answer to -2(-6) is 12.
