None without applying any binary operations because repeated use of a digit does not alter the cardinality of a set.
If you can use operators, the answer depends on which operators and how they may be combined.
The set of numbers that begin with the number 1 is Natural Numbers.

No, zero is a whole number, but not a natural number.The natural numbers are the set {0, 1, 2, 3, ...} (or the set {1, 2, 3, ...})The whole numbers are the set {..., -3, -2, -1, 0, 1, 2, 3, ...}The set of whole numbers has twice as many members as the set of natural numbers, so the answer to your question is NO.
999-111=888 888 3 digit numbers can be made with numbers between 1 - 9
it is 9 because other numbers are made up by the same numbers already used 1-9 for example
There are two numbers, 7 and 49, whose smallest prime factor is 7 in the set of numbers from 1 to 100.
Infinitely many. In fact, there are more irrational numbers between 1 and 2 as there are rational numbers - in total. The cardinality of this set is Aleph-0ne.
There is no special name for this set, so just call it "the set of prime numbers from 1-100".There is no special name for this set, so just call it "the set of prime numbers from 1-100".There is no special name for this set, so just call it "the set of prime numbers from 1-100".There is no special name for this set, so just call it "the set of prime numbers from 1-100".
A number belonging to the set made up of zero and the natural numbers is any non-negative integer, including zero itself. This set can be expressed as {0, 1, 2, 3, ...}, where zero is included alongside all the natural numbers. Hence, examples of numbers in this set are 0, 1, 2, or any whole number greater than or equal to zero.
Some examples of sets of real numbers include: The set of positive integers: {1, 2, 3, 4, ...} The set of rational numbers: {1/2, -3/4, 5/6, ...} The set of whole numbers: {..., -2, -1, 0, 1, 2, ...} The set of natural numbers: {0, 1, 2, 3, 4, ...} The set of irrational numbers: {√2, π, e, ...}
