9+((9+9)/(9+9)) = 10
1*10**-9s
9 + (9/9) = 10
One way: 99/9 - 9/9
Five 9s:(99 x 9 + 9) / 9 = 100
It is five.
1*10**-9s or 1 ns = 1E-9 s
(99)/(99) +9.
10 times
wait not the discription srry
90 / 9 = 10
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
1 ns (nanosecond) = 10-9s 1s / 10-9s = 109 109 = 1000 000 000 1 second = 1000 000 000 ns (nanosecond)
