Description
The pocket electronic calculator is now familiar to us all. However, these everyday objects were still a novelty in the early 1970s and priced out of the reach of most customers. To our modern eyes, the operation of a calculator is quite simple, at least for basic arithmetic. We just push the buttons and the machine does the hard part for us. Since calculators never make mistakes, we need never worry about what goes on inside.

Behind the buttons and screen lies a complex set of miniature circuits. It is the ability of electronics firms to make smaller and smaller components that has led to the success of the calculator. All the electronic circuits that provide the calculating power can now fit onto tiny ‘chips’ of silicon. By also developing the technology for liquid crystal displays (LCD’s), manufacturers were able to shrink calculators even further. When solar power arrived towards the end of the 1970s they could even be made without batteries. Prices fell whilst popularity soared.

Despite all this technology, successful use of the calculator still relies on the knowledge of the operator. The latest machines pack in countless functions and require a large instruction manual. Their increasing power has led to debates about their proper use in schools. The widespread use of calculators – at school, home and in the office – has been blamed for falling standards of arithmetic.

This is in contrast with the early days of calculator use. During the 1970s, a number of textbooks were published to encourage people to use what was still an unfamiliar instrument. These would give examples of how calculators could help with anything, from income tax forms to the weekly shopping list!
