Why do we have order of operations rules in arithmetic instead of just strictly evaluating expressions from left to right (possibly with parenthesis for grouping if we really wanted to change the order)?

My son is 10 years old and going into 5th grade in the fall (but he usually does 6th grade math). He likes Stack the States, and we're looking for a math app with similar appeal. We already have Sushi Monster and his younger sister loves it, but I'd like something more challenging for him.

I'm a pure mathematician with a Ph.D. and I'm currently a visiting professor at a large state university. However, I'm looking to switch gears and get into the quantitative finance field. The problem is that I don't know anything at all about finance. I know that there are companies such as D. E. Shaw that hire mathematicians that don't have financial experience; what other companies should I look at? Is there any general advice you'd give someone in my position? Also, I have my Ph.D. from a well-regarded state school, but I'm not an Ivy-leaguer; does that put me at a disadvantage?

Recently, someone described a 10-volume mathematics textbook series to me. The books were written by a single author, an engineer with a name that sounded Greek, and came with full worked solutions to every single problem, making them ideal for self study. Unfortunately, they could not remember its title, and my attempts to find it with Google and Amazon have failed.
Has anyone come across this series?

I have always been horrible at math, but somehow a great programmer. I have found that writing a computer program that demonstrates a certain mathematical concept enables me to better understand the concept. I'm a psych major and I brought this up once in the research lab I've been working in. My prof said he recalls that someone did research and/or created a system in which a student writes a computer program that is pertinent to a certain mathematical concept and upon completion is given the regular math problem (as it would appear in a math class). This enables the student to better understand the math problem, solve, and learn math. Has anyone heard of this or anything similar? A learning system such as this would be a blessing to my education.
Thanks.
