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 meaning of “extensive” in the second paragraph?

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.

Based on the text, we know that the birds...

Butterflies ... insects. With their almost endless variety of colors, shapes, and sizes they are amongst the most and beautiful and easily recognized of insects.

According to the text, what can obviously be seen from the male and female?

Cow

Cows are cattle which belong to Bovidae famili and Bovinae upafamili. Cows that have been neutered and are typically used to plow the field named Ox. Cows are cared primarily for the benefit of milk and meat as human food.

Cows have a scientific name as Bos Taurus. Cows have a gestation period of over 274 days. Average cow lifespans is 15 years. The male weight is typically around 1,100 kg, while average females’ weight is about 720 kg.
