I have rows of tiny buttons waiting for your touch, Though I cannot speak, I help you count and figure much. I can multiply your worries, divide your heavy sums, Yet I have no fingers, and I do not have thumbs. I can turn upside down to spell a cheeky little word, A classic schoolyard trick that you have likely heard.
