Answer:

60 is composite. It's divisible by 3.

Subtract 3, you get 57.

57 is ALSO divisible by 3.

Just a fun fact:

To know if a number is divisible by 3, do a simple divisibility test:

Add all of its digits. Keep adding until you get a digit.

5+7=12

12 can also be added:

1+2=3

AHA! If the digit is 3, 6, or 9, the number is 100% divisible by 3!:)
