  • Get to work Erin! Go for the "A"!

  • for the part where u said it works for any # what about the # 16

  • @SuperGaara1 If you sum the digits to any number and this sum is divisible by 3 then the number is divisible by 3. The number 16 is not divisible by 3 since 1+6=7 and 7 is not divisible by 3. Let's look at 1,458. Notice when you add the digits together we get 1+4+5+8 which equal 18. Since 18 is divisible by 3, this means 1,458 is divisible by 3. This always works! Kung Fu math!

  • Very helpful and easy to understand, thank you. :)

  • Glad I could help. Go for the "A"!
