use the digit 8 four time to make 89
9/9 + 99 = 100
A four and a five
543,210. If you can use them all multiple times, then it is 555,555.
Assuming that you are able to use all four digits as many times as you wish, then there are a total of 256 different numbers available. 4 choices for the first digit, 4 for the second, 4 for the third and 4 for the fourth. 4 x 4 x 4 x 4 = 256If each may only be used once, then the total will be just 24. 4 choices for the first digit, then 3 for the second digit and two for the third digit. The fourth digit will always be the single choice of the remaining digit, so the calculation will be 4 x 3 x 2 x 1 = 24.
use the digit 8 four time to make 89
9/9 + 99 = 100
88 + 8/888 + 8/8 = 89
89 = 88 + (8 / 8)
(4 + 4 + 4)/4 = 3
1050 is the four digit number don't know which mathematical procedure to use it took me 5 mins to make a small C# program and ta-da! that's it. :)) cheers
6 =(4+4)/4+4 problem solved :D
4 =((4-4)/4)+4 problem solved :D
2 =4/(4+4)*4 problem solved :D
