This level crossing Iım pausing at, patient, facing the lowered gates while the bells ring is where I used to pause forty-plus years ago driving my son to day-care. Little more than a toddler, heıd be sitting up in the back on the childıs fitted seat, craning forward to see the train, Hurstbridge to Melbourne packed in the morning (or met on the way home Melbourne to Hurstbridge packed). Count the carriages! What a long train, son. The bells cease, the barriers go up. On then to day-care where Iıd guiltily leave him while I taught not far away, and he, well he got through his day, with other waifs to play or maybe compete with over their snacks and uniformed carersı. He could count, and soon count the hours. Yet only yesterday, I learned there are kids who never cope with numbers, nor learn to tell the time. Weıve all heard of dyslexia well, theyıre calling this dyscalculia! and the teacher was saying some kids even miss out on finger-counting, having no aptitude, or as we say nowadays, lacking the neuro-connections necessary. Feel for them but despair not! Science is showing how these brains can be rewired. Beside, without arithmetic you can still do well in set theory and other mathematical regions (provided youıve got the wiring for them). The train goes through. The bells cease, the barriers rise up, I drive on. Son, youıve been more of a mathematician than I ever was. Counting the carriages passing may have set you ticking. Just now, I lost count of them myself, recalling you and this word new to me, dyscalculia. Max Richards
