Using only sums and differences, and not necessarily all four numbers, 1, 3, 9 and 27 will make all numbers from 0 to 40.
They are prime numbers.
Only the numbers used in binary code are used twice while all the other numbers are only used once. This numbers are alphabetically arranged ..
It is a permutation problem (any number can be used repeatedly), it will become 4 x 4 x 4 x 4 = 256 four digit numbers. If each number can only be used once, then the answer is 4 x 3 x 2 x 1 = 24 four digit numbers.
Any pair of digits (not including 0), can be used to generate 14 four-digit numbers. If one of the digits is 0, only seven will start with a non-zero digit.
There are really only three main counting systems: roman numerals, tallys, and Arabic numbers. Arabic numbers are the simplest to make large number combonations.
The only numbers used in binary are 0 and 1
Lots of different combinations can be used, one being: 1x2x3x15 We can see that in any order we multiply these numbers in it will equate to 90.
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.
prime numbers only be used as encryption keys as in encryption the numbers are coded inj the form of 0s and 1s ,i.e binary form.
Complex numbers are basically "numbers in two dimensions". You can extend them to more dimensions; one superset that is sometimes used is the quaternions, which are numbers in four dimensions.
9,999 if zeroes can be used than it would be 10,999
If each of the numbers 1, 2, 8, and 9, each of which is also a digit, must be used exactly once, the answer is 4 X 3 X 2 = 24. Reasoning: Any one of the four digits may be taken first; any one of the remaining three may be taken second, and either of the remaining two may be taken next, leaving only one choice for the final digit.
They can be used to search for both letters and numbers.

A digit is that which we used to count numbers.
no, only 1 and 3, Factors are used for only whole numbers. Integers are not included when determining if a number is prime or composite since prime and composite are terms used only for whole numbers.
You know that the odd digits have to be in the units places, and the evens in the tens place, so the general solution is: 80 + 60 + 40 + 20 + 9 + 7 + 3 + 1 = 220
You won't learn much of a language if you only learn a few numbers.
They used numbers, and they had a system for representing consonants, but that can only loosely be described as an alphabet.
Pseudocode is typically only used to describe the solutions to large problems. It is used to make complex things simple. If part of your pseudocode included telling someone to add two numbers, you would simply write: num1 + num2
