the imaginary land of numbers… Yes‚ numbers! I bet that would’ve never come to mind. Which brings me to the question: Who thought of them and why? In 50 A.D.‚ Heron of Alexandria studied the volume of an impossible part of a pyramid. He had to find √(81-114) which‚ back then‚ was insolvable. Heron soon gave up. For a very long time‚ negative radicals were simply deemed “impossible”. In the 1500’s‚ some speculation began to arise again over the square root of negative numbers. Formulas for solving

Abstract A complex number is a number that can be written in the form of a+bi where a and b are real numbers and i is the value of the square root of negative one. In the form a + bi‚ a is considered the real part and the bi is considered the imaginary part. The goal of this project is show how the use of complex numbers originates in the history of mathematics. Introduction Complex numbers are very important component of mathematics. They enable us to solve any polynomial equation of degree

Real Number Properties In this assignment we were asked to solve three expressions using the properties of real numbers in order to do so. Each of the real number properties are essential in solving algebraic expressions. Although you may not need to use all of them in the same expression to solve you will need to use at least one. In this paper I will demonstrate the use of the properties and show the steps needed to solve each part of an expression. Understanding the properties of algebra

Tellurium Many historians believed that Franz Joseph Müller von Reichstein was born around 1740’s to 1742 in the Habsburg Empire‚ which later became known as the Austro-Hungary Empire. Müller had many different positions in the Austria-Hungary administration; but he’s most known for being a mineralogist and skilled miner. He started his rode to success by becoming a Markscheider (official mine surveyor)‚ which then lead him to become an Hüttenwerke (royal commission for mining in the Banat). These

“Mesoamerican Vigesimal Number System” In the modern world we use a number system based on ten with a symbol representing zero to nine. Numbers are written horizontally with each number place representing that the number value has exceeded the value of the number place to the right. The Mayans or Mesoamericans used a twenty based number system that is written vertically. According to the Mayans numerical system one dot is equal to one and instead of writing five dots for the number five a line replaces

of “Complex and Imaginary Numbers” and its applications. I chose the topic “Complex and Imaginary Numbers” because I am interested in mathematics that is hard to be pictured in your mind‚ unlike geometry or equations. An imaginary number is the square root of a negative number. That is why they are called imaginary‚ what René Descartes called them‚ because he thought such a number could not exist. In this paper‚ I will discuss how complex numbers and imaginary numbers were discovered‚ the interesting

THE REAL NUMBER SYSTEM The real number system evolved over time by expanding the notion of what we mean by the word “number.” At first‚ “number” meant something you could count‚ like how many sheep a farmer owns. These are called the natural numbers‚ or sometimes the counting numbers. Natural Numbers or “Counting Numbers” 1‚ 2‚ 3‚ 4‚ 5‚ . . . * The use of three dots at the end of the list is a common mathematical notation to indicate that the list keeps going forever.
