The answer is A. What you do first is divide 6 by 3 to get 2 then you bring down your 10-----> 2*10. Then you subtract -5 from 4 ---> 4-(-5) (if the equation looks like this and only this then you just add the 4 and the 5, you can remember this because the subtraction sign, parenthese, and negative sign looks like a big addition sign.) Your answer will be 9 so just bring that sown too! Your final answer is 2*10^9
