1 => I'm not good at Math.

2 => My math teacher wasn't gentle. She always wants her students to understand quickly, grasp all the knowledge of the lesson in a short time.

3=> I learned the concepts of spatial geometry, ... a lot.

4=> I find the calculation not difficult. Only when you don't practice do you see problems.

5=> Children should learn math because it makes it easier for them to get into a good school.
