why can other people do math?

Why can other people do math?  Why am I stuck, sitting in my head, wondering why I can't do 3 x 5. Why can other people write essays?  Why am I the only kid that can't write an essay?  Why do I feel the stares of kids as I raise my hand? The whispers of kids as I ask for help.  The judgement in the eyes of the people that carry the opinion I care about most?  The look on their faces that say 'why can't they do that? It's easy?' as the teacher walks away, even though I still don't know how to answer the question.  Why can other people do math?
