It is true (as long as there are no decimal places after the ones place) because those numbers will always be divisible by 2, 5, and 10.
With exception of the number zero which is neither prime nor composite.
Composite numbers are integers greater than 1 that can be divided evenly by numbers other than 1 and themselves. In the case of numbers up to 100, the unit's digit refers to the digit in the ones place. The claim that composite numbers up to 100 have 1 as their unit's digit is incorrect, as composite numbers can have any digit in the ones place depending on their factors.
Yes except for 2 on its own which is the only even prime number
Yes except for 2 on its own which is the only even prime number.
Prime numbers r ones that can only be multiplied by itself and 1 to get it and composite is everything else
There may not be any fast methods. In fact, composite numbers which are the product of two very large primes are used for public key encryption. This depends on the fact that there is no fast answer to factorising composite numbers.
Yes, all numbers that have 2 in the one's place are composite numbers. In fact, all even numbers except for 2 itself are composite numbers.

Yes except for 2 on its own which is the only even prime number
Since the 0 is in the ones place, it will make the whole number even. An even number is composite because it can be divisible by 2 and other numbers too.
Yes. All numbers with 0 in the one's column are composite, having at least the factors of 1, 2, 5, and itself. The number 0 is also composite, having all numbers as factors.
Yes except for 2 on its own which is the only even prime number
Yes except for 2 on its own which is the only even prime number.
The ones with less than three factors.
A composite number is a positive integer, which has a positive divisor other than one or itself.
Prime numbers r ones that can only be multiplied by itself and 1 to get it and composite is everything else
The prime numbers are 3 and 7 but 1 is not considered to be a prime or a composite number
Composite numbers can have any digit in the ones place: All multiples of 3 greater than 10 will be composite numbers (the first one being 3×4 = 12). The last digit of the multiples of 3 follow the pattern (starting at 12, ending at 39): {2, 5, 8, 1, 4, 7, 0, 3, 6, 9} which includes all the digits {0, 1, 2, 3, 4, 5, 6, 7, 8, 9}. Thus the last digit of composite numbers greater than 10 can contain any digit.
