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 1960s, 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.

What is the main idea of paragraph 3?

A laptop is a kind of computer unit which has the same function as a PC (Personal Computer), but it’s smaller, lighter and of different sizes. Nowadays, most people choose laptops for several reasons.

A laptop is a portable device. This portability is very helpful for our work, study and other activities. We do not need complicated cable installations to activate a laptop. With a laptop, we can do our work anytime and anywhere.

Moreover, a laptop allows us to access the internet in public places which provide free access called hot spot areas. Some people like to use this facility to carry out their tasks.

Finally, a laptop consumes energy more efficiently than a PC does. This device uses a rechargeable battery as a source of electric energy. So, if we prefer using a laptop, it means that we support the government program to save energy. That’s why a laptop has become very popular recently.

The platypus is a semi-aquatic mammal endemic to East to North Australia, including Tazmania. It is one of the five extreme species of mono-dreams. The only mammal that lays eggs instead of giving birth to live young. The body and the broad flat tail of these animals are covered with dense brown fur, that traps a lay including ear to keep the animals warm. It uses its tail for story joy fact. It has webbed feet and the large robbery’s net. These are species that are be closer to those of ducks, then to these any known mammals. Weight varies considerably from 0.7 to 2.4 kg with males being larger than females. And male averages 50 cm total length whiles the female major approximately 45 cm. The platypus has an average temperature of 32 degrees Celsius rather than 37 degrees Celsius that is typical of the placental mammals.

How much does the Platypus weight?

The polar bear is a bear native to the Arctic Ocean and its surrounding seas. An adult male weighs about four hundred to six hundred and eighty kilograms, while an adult female is about half that size. Although it is closely related to the brown bear, it has paws to occupy a narrow ecological niche with many bony characteristics adapted to for cold temperatures, for moving across the snow, ice, open water, and for hunting seals which make up most of its diets. Although most of polar bears are born on land, it spends most of its time at sea, hence its name meaning maritime bear and can hunt consistently only from sea ice. It spends much of the year on frozen sea.

Where did the animal live?

Snakes are reptiles (cold-blooded creatures). They belong to the same group as lizards (the scaled group, Squamata) but from a sub-group of their own (Serpentes).

Snakes have two legs but a long time ago they had claws to help them slither along. Snakes are not slimy. They are covered in scales which are just bumps on the skin. Their skin is hard and glossy to reduce friction as the snake slithers along the ground.

Snakes often sun bathe on rocks in the warm weather. This is because snakes are cold-blooded; they need the sun’s warmth to heat their bodies up.

Most snakes live in the country. Some types of snakes live in tress, some live in water, but most live on the ground in deserted rabbit burrows, in thick, long grass and in old logs.

A snake’s diet usually consists of frogs, lizard, and mice and other snakes. The Anaconda can eat small crocodiles and even bears. Many snakes protect themselves with their fangs. Some snakes are protected by scaring their enemies away like the Cobra. The flying snakes glide away from danger. Their ribs spread apart and the skin stretches out. Its technique is just like the sugar gliders.

Since the snakes are cold-blooded, they…

The anaconda is the largest snake in the world. Also known as the Water Boa, this giant, meat-eater lives in swampy areas of tropical South America. It spends a lot of time in shallow water, hidden from unsuspecting prey. Anacondas are related to boa constrictors. They give birth to 20 to 40 baby snakes at one time. Like all snakes, anacondas are cold-blooded; they have the same temperature as the environment. They continue to grow all their lives, getting bigger and bigger each year. The longest anaconda ever found was 11.4 m long, there are probably even bigger anacondas that have not been seen. Anacondas are greenish-brown with a double row of black oval spots on the back and smaller white markings on the sides.

How many babies does an anaconda give birth at one time?

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.

Whales are sea-living mammals. They therefore breathe air but cannot survive or land. Some species are very large indeed and the blue whale, which can exceed 30 meter length, is the largest animal which lives on earth. Superficially, the whale looks rather like a fish, but there are important difference in its external structure; its tail consists of a pair of broad, flat horizontal paddles (the tail of a fish is vertical) and it has a single nostril on top of its breadth, broad head. The skin is smooth and shiny and beneath it lies a layer of flat (blubber). This is up to 30 meter in thickness and serves to conserve heat and body fluids.
