In Chapter 9, I wasn't surprised to read that there are different types of intelligence. I became aware of this when people would always tell me how smart I was in middle school, and that they couldn't figure out the stuff I could, no matter how hard they tried. I then thought to myself, "Why can't they? What makes me smart?"
I started thinking about the different subjects we had: math, science, history, reading, etc. History had absolutely everything to do with memory. Later in life, say around high school, you start to see a pattern and can begin to make inferences on why things happened once you know how economics works. Back in the day, however, it was all about memorizing events. I wouldn't call having a great memory being smart, but then again I was the only one at the time thinking about this topic.
Out of all the subjects, math dealt with problem solving the most. This is where I thought intelligence came into play, because even if it isn't exactly 2x-10=20, problem solving is a part of our every day lives. Being able to reason and figure things out with efficiency, in my opinion, is the definition of intelligence. Using that definition, it isn't biased towards a certain group of people. No matter where you come from, if you can solve a problem, you can solve a problem.
