let's move over to exponents we have 2 squared so we're going to square the 2 before we multiply it times negative 3 so 2 squared that's going to be a 4 and then before taking this exponent over here it would be easier simplify this over here so we could just do that let's see inside of here you could almost do the absolute value sign as parentheses you're taking the parentheses and then you're going to have to evaluate this expression and then you're going to take it's absolute value so this thing right here 5 minus negative 1 we know when you subtract a negative number that's the same thing as adding the positive version of it so it's the same thing as 5 plus 1 which will evaluate to 6 so lets just rewrite what we have so this is 1/2 times the absaolute value of 6 squared minus the absolute value of negative 3 times 4 now the absolue value of six is clearly 6, 6 squared is going to be 36 so this part right here will become 1/2 times 36 then over here we have minus in the absolute value sign negative 3 times 4 is negative 12 now we want to do multipication before we do subtraction over here so we can safely do this multipication first i can put parentheses around it to show you that we'll do it first so 1/2 times 36 that is going to be 18 and so we have 18 minus the absolute value of negative 12 and what's the absolute value of 12 it's 12 so it's going to be 18 minus 12 which is equal to 6 and we are done
