Not sure what it is you are asking here. Sequence of numbers? names? prime numbers?
All of them. We normally count in decimal numbers and therefore all digits in decimal numbers must be less than ten.
To write the numbers from 1 to 20, we need to count the digits used for each range. The numbers 1 to 9 use 1 digit each, totaling 9 digits. The numbers 10 to 20 use 2 digits each, totaling 22 digits (11 numbers). Therefore, the total number of digits required to write all the numbers from 1 to 20 is 9 + 22 = 31 digits.
-- The decimal system (base-10) uses 10 digits to write all numbers. -- The binary system (base-2) uses 2 digits to write all numbers.
All three numbers are significant digits, so 3.
