my math teather

I have many teather，but my favorite teather is mr。jiang。maybe you"ll say:"what is the teather like?"I"ll tell you:"He is very kink，and he is very worried about his student。Sometimes，he is strict，but he is pationt with us，and he expains things to us over and over again。 

until we understand them。with his help，my result of math is becoming better and better!
