About rehcaethtam
Rehcaethtam is in fact a word riddle of one term about me, which is not a name, but has meaning if doing some transformation. I have been obsessed with Math learning and teaching for many years. And I feel very lucky because such kind of obsession has transformed me into a very happy person with great confidence in myself. Because during my everyday life, I can design some interesting and useful Math worksheet for my students.
I find that my work interests me a lot and it also has great significance to me and my students. Therefore I can say for certain that my obsession has already become my faith. I will keep the faith, which would never fade. Besides Math learning and teaching, I am also addicted to Mechanical puzzles solving and studying.
