Button Backward

english Arnold put 50 dollars in the bank. During the month he withdraws as shown opposite. He was eventually surprised to see that the balance column adds to $51.00 instead of $50.00. It isn’t interest, so where did the extra dollar come from?
francais Arnold a placé 50 dollars en banque. Au cours du mois, il effectue des retraits comme illustré ci-contre. A la fin du mois, il est surpris de constater que la somme des retraits dans la colonne des débits s’élève à 51.00 $, au lieu des 50.00 $ attendus. Vu que ce ne sont pas des intérêts, d'où vient-il donc le dollar supplémentaire?
