99+sqt9xsqt9/9
99/9=11
9 / 9 + 9 = 10.
99 + (99 / 99) = 100
To make 10 using five nines, you can divide one of the nines into two parts. For example: 9 + (9/9) + 9/9 + 9/9 + 9/9 = 10.
99 + 9(9 - 9)= 99 + 90 = 99 + 1 = 100
( 9+9+9) / (9+9+9)= 1 or 999 /999 = 1
9 + (99/99) = 10 or (9 / 9) + (9 - 9) + 9 = 1 + 0 + 9 = 10
(55-5)/(5+5)
999 + 9/9 = 1000
5-5+5-5+5 equal to 5
.5 after each of them.
