Ok, I gotcha. We can start with an example problem(I do lots of those btw): -2(-3)-1

 

 

Ok, Let's split it into it's parts. (-1*2)*(-1*3)*(-1)

 

We see two negative 1s, so let's multiply those and get rid of them. Now we have (2)*(3)*(-1)

 

2*3=6, so now we have (6)*(-1).

 

6*-1=-6.  

 

Do you see how it works?

 

Try this problem: -3(-4)-1
