My homework says name a 2 digit odd number that is prime. name a 2 digit odd number that is composite.

2 digit meaning that it has 2 numbers. For example, 66 is a two digit number.

Now, they also said it must be prime, meaning that its factors can only be 1 and itself.

Also, it must be odd.

Answer: 67

Now, do the same, except the number must be composite, as meaning that it has other factors.

Answer: 21
