Thinking Mathematically Short Essay: Understanding Mathematics and Linguistics How is Mathematics and Linguistics related with each other? Linguistics is the science of language. Linguists seek to understand the proper uses of natural human language. How languages are structured‚ how and why they vary and change‚ how they are acquired‚ and how people‚ in communicating use them. Mathematics on the other hand is the language of science.

Perfect numbers Mathematicians have been fascinated for millenniums by the properties and patterns of numbers. They have noticed that some numbers are equal to the sum of all of their factors (not including the number itself). Such numbers are called perfect numbers. A perfect number is a whole number‚ an integer greater than zero and is the sum of its proper positive devisors‚ that is‚ the sum of the positive divisors excluding the number itself. Equivalently‚ a perfect number is a number that is

The ecological complex is used to describe broad urban change in cities. The ecological complex identifies the relationship between four concepts‚ known as “POET”‚ population‚ organization‚ environment‚ and technology. Detroit was affected in many different ways by POET between 1900 and 1910 and also between 2000 and 2010. Population refers to the number of people or growth in cities. Between 1900 and 1910 the population of Detroit grew rapidly because of the advancement in technology at the

NUMBER SYSTEM Definition It defines how a number can be represented using distinct symbols. A number can be represented differently in different systems‚ for instance the two number systems (2A) base 16 and (52) base 8 both refer to the same quantity though the representations are different. When we type some letters or words‚ the computer translates them in numbers as computers can understand only numbers. A computer can understand positional number system where there are only a few symbols
