The digits to numbers that you can divide by three always
add up to a number that you can divide by three. For 12,
2 + 1 is 3; for 18, 8 +1 is 9; for 51, 5 +1 is 6. (When
you have to reduce fractions, math problem makers love to
put 51 in there. Now you know! Three goes into it!!!)
Remember, an odd times an odd number gives you an odd number.
If there's an even number there, the answer will be even.
