How to choose calculators
• The main thing to bear in mind when choosing a calculator is that there are several different types, each with a specific purpose. Basic calculators are the simplest tool, suitable for small to medium calculations.
• Scientific calculators offer more functions, allowing you to tackle algebra, statistics, or calculus problems with ease. There are also financial calculators, which are used in professional settings to enter data and receive real-time results.
• Size is another factor to consider, with the most portable calculators today featuring solar cells. They can be tucked away into your purse or wallet, for easy equations on the go.
• Screens vary depending on the size and type of calculator. You can choose from numbers-only type faces and alphanumeric models.
