Thats what i got. Let me know if its wrong :)
Here is a trick that not a lot of people know
(# of terms)*(first+last)/2
(in case you don't know, * means multiply and / means divide)
Remark
The order is not quite correct.
- 7 + (-11 * 5 - - 7) ÷ - 6
The - - 7 becomes a plus
- 7 + (- 55 + 7) ÷ -6
This is where the real problem is. -55 + 7 goes down. This gives - 48
- 7 + [( - 48) ÷ - 6]
You do the division by - 6 before adding. Adding - 7 to the result of the division is your very last step. Think BedMas.
-7 + (8)
The 8 is the result of the division. -48/-6 = 8. the -7 and the 8 are added. You get 1.
