Probably: 9-(-1) = 10
1 - 1/10 = 9/10
NOTHING
It is possible to take negative 1 from nine.It is like getting a loan forgiven. You would be ahead.9-(-1)=10
10
(4*10) + (9*1)(4*10) + (9*1)(4*10) + (9*1)(4*10) + (9*1)
I'm not quite sure if this is what you mean but: 9/9=1 9+1=10 9/9=1 10*1=10 The whole thing: (9/9)*(9+(9/9))=10
9/10 minus 1/10 is 4/5
-1
.9 1 X 9 = 9 = .9 10 10
67 minutes, or an hour and 7 minutes 10 kilometers / x hours = 9 kilometers/1 hour x hours = 10/9 hours = 1 1/9 hours
9*11 = 9*(10 + 1) = 9*10 + 9*1 = 9*10 + 9.
10+9+(9-7+1+1+1)
