Per quanto posso ricordare, ho sempre trovato più facile aggiungere e sottrarre i numeri da sinistra a destra invece che da destra a sinistra. Aggiungendo e sottraendo i numeri in quel modo, ho scoperto che potevo dire le risposte ai problemi ti matematica in classe molto prima che i miei compagni mettessero giù la loro matita. E io non avevo neanche bisogno della matita!
