I have recently inherited a Olivetti Electromechanical calculator. I cannot add two plus two and have it turn out to 4. What are the entry requirements to add and subtract or mutiply and divide. This information would help me tremedously in explaing to my 8 year old daughter how things from the past work as well as the new stuff. Thanks
