It is often said that if a child is not educated in language after critical stage in his development, he is permanently impaired in that regard. I would like to make an addendum to that remark: The same can be said for the field of mathematics, and I am living proof.
The very first instant in which I was introduced to Algebra was when I was in Year 10 or at sixteen years of age. Coincidentally, Algebraic mathematics is introduced to those of ten years of age (or Year 4). Yes, I was a terrible student. Never listening in class, getting into fights, talking back, you name it. In fact, the reason why my English is not at a similar level to my Numeracy can solely be attributed to myself arguing and debating classmates, and teachers.
Anyway, I digress. How would I be able to solve these questions?
