Easy just do the negitive numbers and then try to add to the greates number
The answer could be
-1287
im not sure
Nine and a half times.
***
you can put it fully nine times. You reach 18 like this. But you have 1 more to go until 19! So, just cut the 2 in half to get 1, and put that in!
Rotate once to the left side
This would be 1,711,596.
hope this helps!
