Calculators are tools that help us solve math problems. Simple calculators add, subtract, multiply, and divide. More sophisticated calculators can be used for algebra, geometry, and other higher-level math.
A disability might make a regular calculator hard to use. Adapted calculators have been developed to meet a variety of functional needs.
Calculations can also be made on smartphones, tablets, and other smart home technology. On smart devices, you can ask Siri or Alexa to do simple calculations, such as addition and division. You can also download apps that talk, have large buttons, and high contrast colors. These apps are not just useful to folks with vision impairment. They may also benefit people with learning disabilities or conditions such as ADHD.
What types of calculators are there?
- Large button calculators with high contrast
- Talking calculators, like the Sci-Plus graphing and scientific calculator
- On-screen calculators
- Calculators built into computer software (on-screen), like Premier to Go
- Calculators built into refreshable braille displays, like the Braille Edge
