I am poor in math during school.
Come to think of it, this "handicap" extends to life after school as well.
How bad is my math?
When doing additions and subtractions, I have to use all the digits of my toes and fingers. Looking down at them, the max I can count is up till 21. Oh behave!
(Clueless female readers may want to remember I am a guy)
I've never learned my multiplication tables. So if people ask what's 7x4, I'll mentally go: 7, 14, 21, 28... Talk about slow processing!
So when mobile handphones come with the calculator function, I was the happiest people on earth! After sms, the calc function is my next most frequently used app!
I hated math so much that when I got streamed into the pure science stream after secondary 2, I switched into the sub-science stream so I can skip additional math for history.
I am better with words and pictures (or imagery).
Of course with that decision, I realised after O' levels quite a few courses were closed to me without additional math - thank goodness for that! That made quitting school all the more easier.
It was years later that I learned about left and right-brained persons. I am more right-brained.
It's true, when it comes to investing, all I ever needed was: + - X /
OK, understanding ratio is also great for making bets on soccer or gambling. I guess the same applies for making risk/reward analysis for speculative trades or investments.
Percentage is another way of representing ratio; but given a choice, I prefer to count in money when it comes to gains or losses in my speculations - thank you very much!
"Only" 10% loss is something else if it equals to $100,000 hair-cut. 500% gain crashes down to earth if it means $5,000 profit in money terms. Statistics and numbers do lie.
Of course being poor in math has many handicaps during my investing and trading journey. For eg, options is beyond me :(
Concept I understand; but once I've looked at the Black-Scholes model, I cried.
So I am limited to simpler "products" and trading/investment strategies. Boo hoo hoo.
But looking back, it wasn't a handicap for me. Simple as simple does suits me just fine :)
