31 = 3 + 33 + (3/3).
468, 486, 648, 684, 846, 864.
24 = 4*3*2*1 of them

874321 is the largest number made from all these digits.

18
That depends a lot on how often you may repeat each digit, and what operations are allowed. If you just want to write a four-digit number, using each digit once, start by writing the largest digit on the left, then continue with the second-largest, etc.

I have no idea can someone tell me
The answer is 3*3*2*1 = 18. If the leading digit is 0 it is not a 4-digit number.
5.05 is equivalent to 5.05. No other number is equivalent, though you might write the number in different ways, i.e., using different expressions that evaluate to that number.
The biggest 4 digit number that can be made from using the digits of 850236, using a digit at most once, is 8653.
Function sum_odd_digits(ByVal number As Integer) As Integer Dim digit As Integer sum_odd_digits = 0 While number <> 0 digit = number Mod 10 If digit And 1 Then sum_odd_digits = sum_odd_digits + digit number = number / 10 End While End Function
the answer is = first 2-digit number by using 48= 28,82 and in 3 digit is=282,228,822,822
