Calculator Confidence: 80% Arrow up

An electronic calculator is a small, portable electronic device used to perform operations ranging from basic arithmetic to complex mathematics.

Arithmetic Confidence: 75% Arrow up

Arithmetic (from the Greek arithmos, "number") is a branch of mathematics that consists of the study of numbers, especially the properties of the traditional operations between them—addition, subtraction, multiplication and division.

Arithmetic is an elementary part of number theory, and number theory is considered to be one of the top-level divisions of modern mathematics, along with algebra, geometry, and analysis.

The terms arithmetic and higher arithmetic were used until the beginning of the 20th century as synonyms for number theory and are sometimes still used to refer to a wider part of number theory.

Smartphone Confidence: 73% Arrow up

A smartphone is a mobile phone (also known as cell phones or mobiles) with an advanced mobile operating system that combines features of a personal computer operating system with other features useful for mobile or handheld use.

Smartphones, which are pocket-sized, typically combine the features of a mobile phone, such as the abilities to place and receive voice calls and create and receive text messages, with those of other popular digital mobile devices like personal digital assistants (PDAs), such as an event calendar, media player, video games, GPS navigation, digital camera and digital video camera.

Smartphones can access the Internet and can run a variety of third-party software components ("apps" from places like Google Play Store or Apple App Store).

They typically have a color display with a graphical user interface that covers more than 76% of the front surface.

The display is almost always a touchscreen and sometimes additionally a touch-enabled keyboard like the Priv/Passport BlackBerrys, which enables the user to use a virtual keyboard to type words and numbers and press onscreen icons to activate "app" features.

World Wide Web Confidence: 71% Arrow up

The World Wide Web (abbreviated WWW or the Web) is an information space where documents and other web resources are identified by Uniform Resource Locators (URLs), interlinked by hypertext links, and can be accessed via the Internet.

English scientist Tim Berners-Lee invented the World Wide Web in 1989.

He wrote the first web browser computer program in 1990 while employed at CERN in Switzerland.

The Web browser was released outside of CERN in 1991, first to other research institutions starting in January 1991 and to the general public on the Internet in August 1991.
