I've learnt that the sum of 2 odd numbers produces an even number I've learnt that prime numbers can only be divided by 1 and by itself I've learnt the method to find out whether a number is a prime number or not

i learnt: 1)the sum of two odd numbers give an even number 2)2 is the smallest and only even prime number 3)how to find whether or not a number is a prime number

1) 2 odd numbers produces an even number. 2) Prime numbers are numbers that can only be divisible by 1 and itself. 3) Found out how the number is prime or not.

1) The definition of prime numbers- a number that only can be divided by 1 and itself 2) Prime numbers must be greater than 1 (1 cannot be a prime number as it is not greater than 1) 3)The sum of 2 odd numbers produces an even number. e.g 7+11=18

Yang Ying, just to edit your last point, sure two odd equals one even - 9+9=18, but what Mrs Sin was reinforcing was probably the fact of 2 odd prime numbers equals one even. 11 and 7 are prime, you see.

I learnt: 1) The definition of a prime number 2) How to figure out if a number is a prime number or not. 3) Every prime number is an odd number except for 2.

1. A prime number is a number that can only be divided by itself and 1. 2. 2 is the only even prime number. 3. The sum of two odd prime numbers is an even number.

I have learnt: 1) What is a prime number 2) The characteristics of a prime number 3) How to know if a large number is a prime number & a method on identifying prime numbers

i learned 1)the prime number is a number that can only be divided by 1 and itself 2)about the sieve of eratosthenes 3)a method to identify prime number

I have learnt, 1] what is a prime number 2] prime numbers can only be divided by 1 and itself. 3}When two prime numbers add together will give an even number.

I learnt that 1)A prime number is always bigger than 1 and can only be divided by itself and 1. 2)2 is the only even prime number. 3)To find out if a certain number is a prime, square root the number and divide by the primes smaller than the square root(ed) number, if it is divisible, it is not a prime, if it is not divisible, that certain number is a prime.

1) By using the Sieve of Eratosthenes, prime numbers can be spotted easier 2) 1 is not a prime number 3) 2 is a prime number even though the number is even.

Yin Mon, two odd numbers multiplied together is equal an even number. 2 is the only even Prime number.

DeleteOops I mean added together. Sorry I typed wrongly.
