In the US all students attend university prep high schools. All students take classes which are supposed to prepare students for college.

Is this true for your country?

With the need for so many relatively high level of math teachers, is there any wonder how so many bad math teachers we have in the US?

I witnesses one 8th grade math teacher teach his students that the ratio for volume of cylinder to cone with same height and radius is two to one. I asked him why he believed this is true and he said, "because a cylinder has two circles and a cone has one."

He also told his students that there is no way to know which sides are corresponding if triangle abc is similar to triangle rst.

Why is he teaching math? Because the US tries to teach so many kids.
