The number of 9's between 1 and 100 is 19.
So only using 19, you could do (1+9)^2 to make 10^2 = 100
-Peji
So...what, we've got 20 9s here? Let's see:
09 - 1
19 - 2
29 - 3
39 - 4
49 - 5
59 - 6
69 - 7
79 - 8
89 - 9
90 - 10
91 - 11
92 - 12
93 - 13
94 - 14
95 - 15
96 - 16
97 - 17
98 - 18
99 - 19 & 20
I've got a cheap one then:
(9+9+9+9+9+9+9+9+9)/(9+9+9+9+9+9+9+9+9)+99
Of course, I've been playing four fours recently, so I don't know that concatenation is allowed.
29 + 29 + 9^2 - 39
(9+9+9+9+9+9+9+9+9+9)/9)+
(9*9+9)-(9*9+9)+(9*9+9)= 100
20 9's
(9+9+9+9+9+9+9+9+9+9+9) + (9*9*9*9)/(sqrt(9)*sqrt(9)*9*9*9)
(9*9+9)+9/9
Using all the 9s between 0 and 100 to make a sum of 100 could be solved in many ways. One of which is [(9+9)-(9+9)-(9+9)+(9+9)+9)]/[(9+9)-(9+9)-(9+9)+(9+9)+9)]+99=100
The question says that you use the number of 9's you find between 1 and 100 to make 100. The number of
9's between 1 and 100 is
20. 20*5=100
-Dillon
9^2+9=100
There are 19 number's of 9 from 1 to 100
Using only 19, you could multiply 19*(1+9) to make 190 and then devide by 1.9. Thus, giving you 100
20*5=100
9x9=81
+9=90
+9=99
+(9/9)=100
(9*9)+19=100
99-9= 90
90/9 = 10
(99-9)+((99-9)/9) = 100
Simplify it people.
(999999999/999999999)+99=100
ok, its a simple word trick it says "using the number of nines between 1 and 100" the total number is 20, so 20*5
91+9=100
9/9 + 99
ok its like this:there are 20 9s in 100 but u cant make a hundred with the 9x table so u do:
(9+9+9+9+9+9+9+9+9)/by that again wich is 1 then add 99=100
u dont have to be stupid to work it out
9 9 9 9 9
9 9 9 9 9
9 9 9 9 9
9 9 9
How about...
9/9+99*9^9/9/(9.9-9)/99/9/(9.9-9)/9^9+99=100
OR
9*(99/999.9)^9.9+99+9/9+9*(9/99.9)^9.9=100
9 999 999
9 9..9 9.9
9 999 999 = 100 lol
you all suck i am
a grumpy old man
that knows nothing
about ths crap
i meen look at my englidesh
your wack joe
the answer i100000000000000000000000000000000000000000000000000000000000000000000000^9
i have know clue just like joe
ANSWER
