Four digit numbers span from 1000 to 9999. This totals (9999-1000) +1 = 9000 different four digit numbers
6*5*4*3*2*1=720
There are infinitely many. For example, 14,104,1004,10004,100004 etc.
Their order is switched. For example, in the two numbers 12345 and 13245, the second and third digits are transposed.
How do i multiple double digits for example 73×28
That 's not possible since irrational numbers have infinity digits. All whole numbers are rational.
6*5*4*3*2*1=720
There are 24 number made by permutations of the digits. There are lots more if the digits can be repeated, for example, 27335722. Even more can be made by using arithmetic and algebraic operations, for example 35^27 = approx 4.8960*10^41. You have not specified what the rules for "making" numbers are!

an arrangement of data for 2-digit numbers , the tens digits are shown as the "steams" and the ones digits as the "leaves" Example: 19,22,25,26,27,28,29,30,34,36,37,42,43,44,46,48,48,49,52,53,55,57,58,62

Numbers formed should be of at least 3 digits means they may be of 3 digits, 4 digits, 5 digits or 6 digits. There are 6 choices for digit in the units place. There are 5 and 4 choices for digits in ten and hundred’s place respectively. So, total number of ways by which 3 digits numbers can be formed = 6.5.4 = 120 Similarly, the total no.of ways by which 4 digits numbers can be formed = 6.5.4.3 = 360. the total no. of ways by which 5 digits numbers can be formed = 6.5.4.3.2 = 720. The total no.of ways by which 4 digits numbers can be formed = 6.5.4.3.2.1 = 720. So, total no.of ways by which the numbers of at least 3 digits can be formed = 120 + 360 + 720 + 720 = 1920.
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.
For Example: -5,0,5 |-5| |0| |5|
Digits in math problems are just simply numbers. For example, if there a number like 4123, the digits would be 1, 2, 3, 4. It is also good to write them in orders.
10 digits are numbers in the billions.
