Honestly, an infinite amount can be made. It could be decimals (4297.5, 3.0245, 4.12), whole numbers (54313, 4021, 318), negatives (-42241, -703, -2754), negative decimals, etc.... AND each of those numbers can be negative, and have a decimal formation, and have a negative decimal formation, so there really is no limit.

I assume you mean how many 4-digit numbers can be made from a set such as {A,A, B, C} where A, B and C are single digits. There are 12 such numbers.

There are infinitely many. For example, 14,104,1004,10004,100004 etc.

There are 5460 five digit numbers with a digit sum of 22.
Five... 0,2,4,6 & 8
Because 10.00400 is 10.004, this has five significant digits (numbers).
It has six letters and five numbers.
ther are five significant digits in that number.
