Work Step by Step

We are given the expression $-5+3(-2)-(-12)$. According to order of operations, we must perform multiplication before adding and subtracting. $-5+3(-2)-(-12)=-5+(3\times-2)-(-12)=-5+(-6)-(-12)$ Next, we can add and subtract from left to right. $-5+(-6)-(-12)=-5-6-(-12)=-11-(-12)=-11+12=12-11=1$
