If you have experienced the excitement of a group of children who realize they will be using a hand calculator, you will agree that the calculator should have a role to play in the elementary school classroom. In stant motivation! The most “ reluctant” learner is anxious to have a chance to use the calculator.

The first section 'Introduction to pocket calculator analysis' is an extended review of styles of calculator together with some techniques of operation and formulae for functions, mostly standard on any scientific calculator. Sections 2 and 3 contain methods and standard numerical formulae with some key stroke sequences for evaluation.

The first author discovered the property below while playing with his pocket calculator, and the second author then tried to find out what was behind this property. We enjoyed this voyage of discovery and thought that you might like to share it with us. Actually, a calculator is not essential, but you will need a square array like in front of you. If your calculator looks different, that is no problem: all standard keyboards will work just as well.

Previous research on calculator use in standardized assessments of quantitative ability focused on the effect of calculator availability on item difficulty and on whether test developers can predict these effects. With the introduction of an on‐screen calculator on the Quantitative Reasoning measure of the GRE ® revised General Test, it is possible to explore calculator use in more detail. This study investigates calculator usage for the GRE examinee population across examinee and item characteristics. Results suggest that calculator usage in the GRE is very common (75% of responses used a calculator) but is less prevalent for low and high ability examinees and for male, Black, and Hispanic examinees. Items associated with lower levels of calculator usage tended to be more difficult, required less time to answer, and did not present a real‐world application. Quantitative comparison items were also associated with less calculator usage, but other item type and content distinctions showed small differences in usage. Most items exhibited a positive relation between calculator usage and response accuracy (after controlling for examinee ability), that is, responses that used the calculator were more likely to be correct. Items that did not show an association between calculator use and accuracy tended to be easier and had less overall usage of the calculator.
