Answer 10

Composite numbers, are the opposite of prime numbers.

Composite numbers:
\(\normalsize\color{blue}{ \rm 4 }\) (can be divisible by 2)
\(\normalsize\color{blue}{ \rm 6 }\) (can be divisible by 2 & 3)
\(\normalsize\color{blue}{ \rm 8 }\) (can be divisible by 2 & 4)
\(\normalsize\color{blue}{ \rm 9 }\) (can be divisible by 3)
\(\normalsize\color{blue}{ \rm 10 }\) (can be divisible by 2 & 5)

and \(\normalsize\color{blue}{ \rm etc., }\)

Answer 11

prime numbers would be starting like:
\(\normalsize\color{blue}{ \rm 1 ,~2,~3,~7,~11 }\) and \(\normalsize\color{blue}{ \rm on... }\)

these numbers can be only divided by \(\normalsize\color{blue}{ \rm 1}\) and by the \(\normalsize\color{blue}{ \rm number~~itself.}\)

Answer 12

1 is not prime, Zelman.

Answer 13

Well, 1 can be only divisible by 1 and itself, but I guess, it is not prime, just by a definition. Right, 1 is not a \(\normalsize\color{blue}{ \rm prime. }\)
