Math

Math is a tough subject in our Deaf classrooms but I got to challenge you on this interesting question of the day, multiply any numbers by nine then add up  its digits and you'll always get a nine:

____ x 9 = ____
____ + ____ = 9

Select any numbers at random:

  3 x 9 = 27

Add up its digits:

2 + 7 = 9

Let me try it again using my zip code:  34744

34744 x 9 = 302,696

Add up its digits:

3 + 0 + 2 + 6 + 9 + 6 = 27

Keep on adding its digits until you get a singular digit:

2 + 7 = 9

Now it's your turn!
