Psychology
Positive transfer occurs when a new stimulus (S) is attached to a previously learned relationship between an S and a response (R). For example, positive transfer occurs when you learn multiplication after you have learned addition. Suppose you learn that 2 + 2 = 4. The "2...

It is not a prime number?

math process
If the numbers are both odd and add to 10, they can be 9 and 1 or 7 and 3, but not 5 and 5, since that has no remainder when divided by 5. That leaves you with four possibilities. Speedo has it.
