88 + 8/8 = 89
To create the number 89 using the digit 8 four times, you can express it as 88 + 8/8. This translates to 88 + 1, which equals 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.
To create the number 89 using the digit 8 four times, you can express it as 88 + 8/8. This translates to 88 + 1, which equals 89.
9/9 + 99 = 100
88 + 8/888 + 8/8 = 89
89 = 88 + (8 / 8)
(4 + 4 + 4)/4 = 3
To form a four-digit number using the digits 0, 1, 2, 3, 5, 6, and 7, we must ensure that the first digit is not 0 (to avoid creating a three-digit number). This leaves us with 6 options for the first digit (1, 2, 3, 5, 6, 7). For the remaining three digits, we can use any of the 7 digits (including 0) and can repeat digits. Thus, the total number of four-digit numbers is calculated as follows: (6 \times 7 \times 7 \times 7 = 6 \times 343 = 2058). Therefore, there are 2058 possible four-digit numbers.
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
4 =((4-4)/4)+4 problem solved :D
2 =4/(4+4)*4 problem solved :D
6 =(4+4)/4+4 problem solved :D
To find the number of strings of four decimal digits that do not contain the same digit twice, we can use the principle of counting permutations. For the first digit, we have 10 options (0-9), for the second digit, we have 9 options (since one digit has already been used), for the third digit, we have 8 options, and for the fourth digit, we have 7 options. Thus, the total number of such strings is calculated as (10 \times 9 \times 8 \times 7 = 5040).
