9 + (9/9) = 10
Ninety nine divided by nine equals eleven
999 + (999/999) = 1000
You could have one No. 9 or a handful of No. 9s
Nine of them
9.99999999
9 + (9/9) = 10(99/9) - (9/9) = 10
10 times
1*10**-9s
90 / 9 = 10
Take two 9s and make them a fraction like this 9/9. Then put the other two 9s together to make 99 and you get 9/9+99=100. Because 9/9=1 so it becomes 1+99=100.
One way: 99/9 - 9/9
