I have a PhD in engineering. I can do calculus, differential equations, linear algebra, statistics and design of experiments.

But I have ALWAYS had trouble with arithmetic.

Go figure :)

everyone has their strengths and weaknesses. I once called a man to see if he could give me a quick easy measurement over the phone to save a long drive. He told me "Mr. Rightly_Dividing, I have a whole alphabet after my name, I speak 7 languages fluently, but I do not have a technical mind, I can not operate a tape measure"

I am *so* relieved to hear you say that. Math nut here, have that intuitive sense for probability and everything, bomb arithmetic regularly, was a mess the first month of game theory.

Not PhD, but BS and MS, and did weapons development for over 10 years doing Calc, Diff EQs and such every day and I still have trouble adding and subtracting.
