5 odd numbers CAN'T add up to an even number like 50
With 123 digits you can make 123 one-digit numbers.
What is the largest number you can make from the digits 8,6,9,1 explain how you make the number
Ten different digits can be used to make 10C4 = 10*9*8*7/(4*3*2*1) = 210 four-digit numbers. Either numbers starting with 0 are permitted or the 10 digits do not contain a 0.
89,999 different numbers i guess
There are 192.
6 if all digits are different, 27 otherwise.
You can make 24 numbers by rearranging the digits. However, you can make vastly more if you allow mathematical operations on the digits. For example, 3+5*8-6 = 37.
Assuming you are treating each number as a number and not as an individual unit, the numbers you can make from these digits are 899, 989 and 998.
∞ \ Infinite
456, 546 and 564 are three of the four possible even numbers.
2*3*3*3*3 = 162
You can create several different numbers from the digits 1, 3, 4, and 6 in 1346. If you consider all possible combinations of these four digits, you can form a total of 24 unique four-digit numbers (4! = 24). Additionally, you can also create various three-digit, two-digit, and one-digit numbers, which would increase the total count significantly. However, counting all permutations of all possible lengths gives a comprehensive view of the total combinations.
