PRIME NUMBERS EXPLAINED
Prime Numbers are those numbers that can only be divided by themselves and 1.
Example: Tick only the prime numbers
3,4,5,6,11,29,71,50,99
Let's start with 3:
Think of a number that can divide 3 without a remainder. The only 2 numbers are: 3 and 1. Therefore, 3 is a prime number.
Next is 4: 1,2 and 4 (itself) are the numbers that can divide 4 without a remainder. Therefore, 4 is not a prime number.
3✓,5✓,11✓,29✓ and 71✓ are Prime Numbers.
Try this:
Use {✓} for Prime Numbers and {x} for numbers that are not Prime Numbers.
