I don't think it's related to IQ or abstract thinking skills. Maybe you have astonishing skills in other domains but are not suited to mathematical thinking for whatever reasons. Also, the current mathematical language is just a compromise that suits a majority, maybe you are not in it. I find the formulas on the page quite easy to read and to "sense" (I also have a background in cryptography, which helps a lot). I like these expressions, because they are very simple to manipulate, which helps understanding them better, and also to infer more results. However, because I "sense" them, I can always dig down every symbols and know what's behind (eg. the scalar multiplication, k.G, I know it is actually like doing the sum of G+G k times, which in turns results in more operations in the particular field or group that G belongs to, etc). If you study electricity where complex numbers are used a lot for instance, the i symbol becomes very tangible. It is more than a symbol, but a real object with well defined properties, and that you can describe in multiple ways. If you start to learn all these properties and multiple ways, you will understand it better, until it becomes very familiar. Also, you have to understand that i is just not a fancy object, it is actually an object mathematicians created because some operations didn't have results in the set of real (in particular not all polynomial equations had roots). So we extended the set of real with a bigger set (the set of complex, which is actually a two-dimensional set), where these problem disappeared. Later, mathematicians and physicists start to use complex numbers a lot because they could describe many useful properties in a very compact way.
