Marek thinks of 2 prime numbers that are larger than 3. He multiplies the 2 numbers together. is his answer odd or even.

Im thinking it would be odd because when you multiply 2 odd numbers youre result is usually odd

It must be odd. As you know, 2 is the only even prime number. Therefore, all prime numbers have the form (2x+1).

For example, two numbers are 2x+1 and 2x+5. We have:

(2x+1) (2x+5) = 4x^2 + 12x+5

Since 4x^2+12x is even, 5 is odd, 4x^2+12x+5 must be odd.

Good luck!
