You might be one of those people that can do math purely symbolically, by parsing and manipulating expressions, a bit like regular language and you don't need your brain to build a mental image for the things you work with.
I am intuition-first kind of person, and let me tell you, intuition is not a crutch, it can do things where symbol manipulations would take orders of magnitude more effort.
It is actually possible to imagine and manipulate highly-complex, multi-dimensional things that don't have equivalents in nature.
Imagination is a muscle used a lot when thinking intuitively, some of us have it developed to a ridiculous degree.
