Can't calculate a tip or even balance your checkbook?I'm going to need a lot more evidence of this before I believe that 5-8% of the population has a physical issue preventing basic math ability. Gawd, the last thing we need is yet another excuse.
Take heart. Maybe you can blame your brain -- specifically, the parietal cortex in the top back part of the head. It also could be a problem that has roots not in a failed arithmetic or "new math" lesson, but even earlier.
Recent findings indicate that how well 3-year-olds estimate quantities predicts their math ability in elementary school. Another study funded by the National Institutes of Health showed that the innate capacity to estimate is impaired in children who have a math learning disability.
The findings are so new that there's no widely accepted way to diagnose what's known as dyscalculia (dis-cal-KOO-lia), nor any set strategies for coping with it -- even though 5 to 8 percent of the population is thought to suffer from math learning disability. Consider it the mathematical partner to dyslexia, which impairs reading ability.

Can't "Do" Math? It's Not Your Fault.
Blame your parents and grandparents for bad genetics:
