Here is a cracker from a few years back. Have fun.:DQuote:
Use exactly four 9s and any number of arithmathic or higher level math operations to make numbers from 1 to 20.
Example
1=(9+9)/(9+9)
7=(9+9+sqrt9)/(sqrt9)

Can't.......got a headache Wongo.......and I will have until you post the answer
1 = (9+9) / (9+9) ..................................18 / 18 = 1
2 = (sqrt9 * sqrt9 + 9) / 9 ................................18/9 = 2
3 = (9+9+9) / 9 .................................27 / 9 = 3
4 = (sqrt9 * 9 +9) /9.....................36/9 = 4
5
6 = sqrt9 ((9+9) / 9)............................ 3 * 18/9 = 6
7 =(9+9+sqrt9)/(sqrt9)............................ 21/3 = 7
8 = (9 squared - 9) / sqrt9 * sqrt9...........................72/9 = 8
9 = (((9*9) / sqrt9) /sqrt9)..........................81 / 3 / 3 = 27/3 = 9
10 =( sqrt9 * 9 + sqrt9) /sqrt9.............................30 / 3 = 10
11 = (9 squared + 9 + 9 ) / 9.....................99/9 = 11
12 = sqrt9 + sqrt9 +sqrt9 +sqrt9...................3+3+3+3 = 12
13
14 = (9 squared + sqrt9) / (sqrt9 + sqrt9 )......................(81 + 3) / 6 =
15 = sqrt 9 * 9 - sqrt 9 - 9...................3*9 -12 = 15
16
17
18 = sqrt 9 * sqrt9 + sqrt9 *sqrt9...................9+9 = 18
19
20
i'll do the rest later:rolleyes::2tsup:. its to late to think lol:cool:
The "9 squared" bit is a bit dodgy.
What's next 9 thirded, 9 tripled or 9 minus five times four ?? :D
Wongo, please do not peddle this #$%^& as it will give everyone a doody of a headache (Except Sheddie):q
It's fun. Stirlo is enjoying it.:U
9-9+9²/9=9
Anywhere you used 9-squared, just replace it with (9*9).
