It is possible to take negative 1 from nine.
It is like getting a loan forgiven. You would be ahead.
9-(-1)=10
1 - 1/10 = 9/10
-9
There are infinitely many possible answers. Two such are 1 x 9 10 x 0.9
(4*10) + (9*1)(4*10) + (9*1)(4*10) + (9*1)(4*10) + (9*1)
9 over 10 minus 7 over 10 equals 2 over 10. This can be simplified to 1 over 5. So, 9/10 - 7/10 = 1/5.
Probably: 9-(-1) = 10
1 - 1/10 = 9/10
NOTHING

(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

.9 1 X 9 = 9 = .9 10 10
