The magic of the nines
Saw a post this morning regarding the 9’s times tables and some of tricks for remembering them. One of my friends stated, “Why weren’t we taught this in school?” Well I was. Had great math teachers in grade school, who made math fun.
Did you know that if you read the 9’s times tables backward and forward, you’ll see reciprocals
9 X 1 = 9
9 X 2 = 18
9 X 3 = 27
9 X 4 = 36
9 X 5 = 45
9 X 6 = 54
9 X 7 = 63
9 X 8 = 72
9 X 9 = 81
9 X 10 = 90
9 and 90
18 and 81
27 and 72
36 and 63
45 and 54
