1,3,5,7,9 Odd numbers are the ones that if you repeatedly subtract 2 from, you will end with 1. Odd numbers always end in 1, 3, 5,7, and 9. Examples: 23, 37, 51, 69, 75, 87, 99
1, 3, 5, 7, 9

{ [(1+3) *5 ] +7 } /9 = 3 [4 *5] + 7 = 27 divided by 9 = 3 also [ (1+3) / (5+7) ] * 9 = 3 More complex is 13 * (5+7) - 9 = 3 with just signs : -1 -3 +5 -7 + 9 = 3
3 = 1 x 3 5 = 1 x 5 7 = 1 x 7 GCF = 1
