• Dec. 5, 2007 - mirrored images
Emily noticed this morning that the answers to the multiples of 9 mirror each other...
9 18 27 36 45 / 54 63 72 81 90
She asked me if I knew that... I told her no. She said I guess only someone who writes them backwards all the time would see that. There are days when Emily write 81 when she meant to write 18. |
