An electronic calculator is a small, portable electronic device used to perform both arithmetic operations and complex mathematical operations.

The first solid electronic calculator was created in the 1960 s, building on the extensive history of tools such as the abacus (developed around 2000 BC), and the mechanical calculator (developed in the 17^th century AD). It was developed in parallel with the analog computers of the day.

In addition to general purpose of calculators, there are those designed for specific markets, for example, there are scientific calculators which include trigonometric and statistical calculations. Some calculators even have the ability to do computer algebra. Graphing calculators can be used to graph functions defined on the real line, or higher dimensional Euclidean space.

According to the text, what is the usage of calculator?

• To write numbers

• To play music

• To count numbers

• To check number

The synonim of word "extensive" is...?

• Large

• Small

• Tall

• Tiny

The plane with largest wingspan ever built was nicknamed the Spruce Goose. The wingspan of the Spruce Goose was 320 feet (almost 100 meters), and the plane weighed 200 tons. It was so big that it needed eight engines to power it.The plane was designed by Howard Hughes in response to a U.S government request for a plane that was able to carry a large cargo for the war effort. It was made of wood because wood is a less critical material in wartime than metal.The plane was so difficult to build that it was never really used. It was flown one time only, by Hughes himself on November 2, 1947; during that flight, it travelled a distance of less that one mile over the Los Angeles Harbor, but it did fly. Today, the Spruce Goose is on exhibit for the public to see in Long Beach, California.

According to the text, why did the plane need eight engines to power?

• It has the largest metal wingspan

• It was very big and heavy and made of metal

• It was very big and heavy and made of wood

• It has the largest wooden wingspan

What is main idea of paragraph two?

• The cargo plane was made of metal

• The plane was designed to carry a large cargo

• The large cargo was the US government’s plane

• The US government requested to carry’ critical materials

From the text above it can be inferred the text that Spruce Goose ....?

• Was designed by a U.S. soldier

• Was made of less critical material during the war time

• Was a prototype of a war cargo

• Becomes an artifact exhibited in California
