Question

What are prime numbers and integers

Answer 1

actually i always get confused

Answer 2

prime number
A prime number (or a prime) is a natural number greater than 1 that has no positive divisors other than 1 and itself. A natural number greater than 1 that is not a prime number is called a composite number.

Answer 3

integer
A whole number; a number that is not a fraction

Answer 4

so 3,5,7,11,13 are prime numbers

Answer 5

Answer 6

Summer scrambled my brains

Answer 7

integer means 1,2,3..... are integers

Answer 8

An integer is simply a whole number. It has no fractions, nothing after its decimal point (or lack thereof).

Examples:
3
5
7

Examples of numbers that aren't integers:
3.5
\(5\frac{4}{5}\)
-7.8
A prime number is an integer that can only be divided by two whole numbers to form an integer (one and itself).
A few examples:
3 because \(3\div 1=3\) and \(3\div 3=1\)
5 because \(5\div 1=5\) and \(5\div 5=1\)
7 because \(7\div 1=7\) and \(7\div 7=1\)

Examples of numbers that aren't prime:
6 because \(6\div 3=2\) and \(6\div 1=6\) and \(6\div 6=1\)
10 because \(10/5=2\) and \(10\div 1=10\) and \(10\div 10=1\)

Answer 9

cant we say that 6 is a prime number? it is also divided by 6 to get 1
