Wide range of capability

Hewlett-Packard introduced its first desktop programmable calculator in 1968 and the world’s first pocket scientific calculator in 1972. Since then, Hewlett-Packard has introduced several desk-top and pocket calculators with technologically advanced features, each with different capabilities for different levels of problem sophistication. To properly select a calculator, you must consider the problems you’re facing today, as well as the problems you’re likely to face tomorrow.

Pocket calculators

For example, if your main concern is general math - addition, subtraction, multiplication, and division - with an occasional need for log or trig functions, the HP-21 may be just perfect for you.

And, if you occasionally solve repetitive or iterative problems, there are two HP pocket calculators practically ‘custom made’ for you - the programmable HP-25 or HP-55. But, maybe your problems are more business oriented. The HP-22 or the HP-80 can solve virtually all financial calculations involving the relationship between time and money, quickly and easily.

For the ultimate pocket-sized problem solving power in any field. Hewlett-Packard offers you the famous ‘pocket computer’ - the HP-65. Whichever HP pocket calculator you finally select, you can be assured that it is the finest in its class … because HP’s standards of quality permit nothing less.

Desk-top calculators

Hewlett-Packard’s desk-top programmable calculators are fast becoming business and industry’s most popular computing device because they combine computer-like power with convenience and ease of operation.

Selection of the correct desk-top calculator for you is a more subtle operation. There are different programming languages to choose from - a step-oriented language, an algebraic language and a formal computer language - BASIC.

There are varying memory sizes, data handling capabilities. read-only-memory options, interface cards, and compatible peripherals. The options and alternatives are many, allowing you the most flexibility possible in configuring a computing system that best fits your needs.
