This is a very subtle subject matter.  I am high in Trait Openess.  Consequently I need to constantly reformulate how everything pieces together.  I have a diverse and intense interest in the world.  <br><br>BUT, there are some simple things that continue to flummox me!<br><br>I've been trying to reason how I can predict the length of a ramp knowing it's gradient and the change in height from one end to another.<br>I remember how to calculate it, but I don't know why doing that gives me the correct answer.  <br><br>So, not gifted at understanding mathematical relationships, but able to envision/model concrete scenarios in my head.
